10 Delicious Plant-Based Bento Lunch Ideas
These easy-to-make bento meals are nutritious, affordable, and perfect for work, school, or travel. Each option balances proteins, grains, and vegetables while being visually appealing and time-saving.
1. Mediterranean Chickpea Salad
The Mediterranean diet continues to inspire many UK households because of its balanced and fresh ingredients. Combine cooked chickpeas with chopped cucumber, cherry tomatoes, red onion, and olives, then toss with lemon juice and olive oil. Add a portion of couscous or quinoa for extra fibre and energy. A small container of hummus and vegetable sticks such as carrots or peppers completes this nutritious lunch.
This is a vibrant, protein-rich option that travels well in bento boxes for adults, keeping you energised through the workday.
2. Asian-Inspired Tofu Rice Bowl
Tofu remains a staple in many plant-based diets because it is high in protein and easy to flavour. Lightly fry tofu cubes in sesame oil until golden and serve with jasmine or brown rice. Add steamed edamame, shredded carrots, and a drizzle of soy-ginger dressing.
Pack it in a stainless steel bento box to maintain freshness and prevent spills. The result is a nutritious, high-protein lunch that satisfies without feeling heavy, suitable for both professionals and students.
3. Classic Avocado Wrap
For a quick lunch on busy mornings, prepare soft tortilla wraps filled with smashed avocado, lettuce, cucumber, and roasted peppers. To add variety, include a small side of fruit such as kiwi, strawberries, or grapes.
This meal is light, rich in healthy fats, and perfect for those searching for easy vegan lunch meals. It’s a convenient option that can be prepared the night before without compromising taste or texture.
4. Sweet Potato and Lentil Power Box
Roasted sweet potatoes paired with seasoned green lentils make a satisfying base for a nourishing lunch. Add a handful of spinach or kale for greens and drizzle with tahini or lemon dressing.
This combination delivers long-lasting energy and is especially good for anyone following a fitness or gym routine. Lentils and sweet potatoes are both rich in iron and fibre, supporting a balanced diet that aligns with the growing UK trend of nutritious home-prepared lunches.
5. Rainbow Vegetable Sushi
Sushi rolls can be completely plant-based and fun to make. Fill sushi rice and nori sheets with thinly sliced cucumber, avocado, red pepper, and carrot. Slice into bite-size pieces and serve with a small pot of soy sauce, pickled ginger, and edamame beans.
This colourful meal is visually appealing and ideal for bento lunch boxes for kids. It encourages children to eat more vegetables while enjoying an exciting, hands-on lunch experience.
6. Quinoa and Roasted Vegetable Bowl
Quinoa is a complete plant protein and an excellent substitute for rice. Roast a selection of seasonal UK vegetables such as courgette, aubergine, and red peppers, then mix them with cooked quinoa. Add fresh herbs like parsley or basil and a squeeze of lemon for flavour.
This dish stores well in any lunch box with food compartments, making it perfect for meal prep. It delivers balanced nutrition, combining whole grains, protein, and fibre in one convenient serving.
7. Falafel Snack
Falafels are a staple of many plant-based diets. Combine homemade or store-bought falafels with whole-grain pita slices and a vegan yogurt or tahini dip. Include raw vegetables such as carrot, celery, or cucumber sticks for crunch.
This is an excellent portable lunch that requires minimal preparation. It is also a smart choice for anyone seeking high-protein, fibre-rich plant-based meals. A few cherry tomatoes or olives add extra freshness and visual appeal.
8. Pasta Salad with Pesto and Vegetables
Pasta salads remain one of the most searched vegan lunch ideas simple enough for meal prepping. Use wholewheat or lentil pasta for added protein and toss with dairy-free pesto, cherry tomatoes, and spinach leaves. For extra depth, add roasted courgette or sundried tomatoes.
This recipe can be served cold, making it a practical lunch during busy office days or outdoor picnics. It is also one of the most affordable plant-based lunches to prepare in bulk.

A combination of black beans, corn, diced tomatoes, and avocado slices creates a colourful and filling lunch. Layer these with brown rice and top with lime juice, coriander, and a mild salsa.
This flavour-packed dish provides sustained energy and satisfies cravings for something hearty yet healthy. It’s ideal for people looking for bento box ideas for adults who want variety without complicated cooking.
10. Sweet Bento Treat Box
A well-balanced lunch can include something naturally sweet. Create a dessert-style bento with almond butter oat balls, fresh berries, and a small vegan muffin or piece of dark chocolate.
This approach satisfies sweet cravings without processed sugar and keeps energy levels steady throughout the afternoon. It’s a thoughtful way to complete a plant-based meal while maintaining nutritional balance.
