Protein and fibre: how to build your lunch bowl
Roasted chicken, warm rice, beans and crunchy vegetables. A good lunch brings several things together: ingredients you enjoy, a portion that suits your appetite and enough variety to make the next bite interesting.
Protein and fibre offer a useful way to think about that combination. Both are receiving attention in food right now, and both can fit comfortably into a bowl built around your favourite meat, fish or chicken.
Why protein and fibre are getting attention
Protein has become a mainstream food trend, highlighted in SIAL’s 2026 food insights. Fibre is also gaining attention: SIAL Paris included a dedicated fibre session in its October programme. For lunch, the practical opportunity is to bring familiar foods containing these nutrients together.
Start with the protein you enjoy
Chicken, beef, fish and eggs are familiar protein foods, as are options such as tofu and pulses. The NHS Eatwell Guide includes meat, fish, eggs and beans within its protein food group.
At Ruba, roasted chicken, steak and salmon have a clear place on our menu. We marinate and roast them in the oven in each restaurant. Their preparation matters: well-seasoned meat or fish gives the whole bowl a flavour direction.
Choose that starting point according to what you feel like eating. Then build the rest of the meal around it, thinking about texture, freshness and the flavours you want alongside.
Build fibre into the rest of the bowl
Wholegrains, pulses and vegetables give you several ways to include fibre. Brown rice can bring it into the base; beans or lentils add another source alongside your protein. The NHS’s practical fibre guidance recommends using a variety of these foods.
That approach leaves plenty of room for taste. Kidney beans work with smoky flavours. Lentils pair well with garlic and fresh tomatoes. Cucumber or finely sliced cabbage brings a crisp contrast to warm rice and roasted ingredients.
When choosing your vegetables, think about what each adds to the bowl: crunch, sweetness, freshness or a little sharpness. A few ingredients that work together can make a more enjoyable meal than adding every available topping.
Three combinations to try
Use these as ideas for a homemade lunch or inspiration when building your own bowl:
Chicken, rice and beans. Pair roasted chicken with brown rice, kidney beans and red cabbage. Finish with a smoky dressing for a warm, savoury combination.
Steak, lentils and tomatoes. Combine steak with rice, lentils, cherry tomatoes and a garlic dressing. The lentils add a soft texture alongside the meat and fresh vegetables.
Salmon, chickpeas and cucumber. Serve roasted salmon with brown rice, chickpeas and cucumber. Add lemon and herbs for a fresh finish.
Make it a meal you want to come back to
Daily preparation is part of how we make this work at Ruba. Our teams start by cooking the rice. Through the day, they marinate and roast meat and fish, chop vegetables and make our dressings in each restaurant. Each component needs to taste good on its own and work with the others.
That was a central consideration when we developed our custom menu: giving customers freedom to choose ingredients that combine well. Nutritious food also needs to be tasty, convenient and realistic to eat regularly.
For your next lunch, choose a protein you enjoy, add a base and vegetables, and try beans or lentils alongside. Finish with a dressing that brings the flavours together.
