Ingredients (serves 2)

Protein & vegetables

  • 300 g chicken breast, thinly sliced

  • 1 red pepper, sliced

  • 1 yellow pepper, sliced

  • 1 small red onion, sliced

Seasoning

  • 1 tsp extra virgin olive oil

  • 1 tsp smoked paprika

  • 1 tsp ground cumin

  • ½ tsp ground coriander

  • ½ tsp garlic powder (or 1 fresh garlic clove, crushed)

  • ½ tsp chilli powder (optional)

  • Salt & black pepper

To serve

  • 2 small wholewheat tortillas

Optional toppings (keep light)

  • 2 tbsp 0% Greek yogurt or Skyr

  • Fresh tomato salsa or chopped tomatoes

  • Fresh coriander

  • Lime wedges

  • Avocado slices (¼ per person, optional)

Method

  • Season the chicken with olive oil, spices, salt and pepper.

  • Heat a large non-stick pan over medium–high heat and cook the chicken for 4–5 minutes until just cooked through. Remove and set aside.

  • Cook the vegetables in the same pan for 3–4 minutes until softened but still colourful. Add a splash of water if needed instead of extra oil.

  • Return the chicken to the pan, squeeze over lime juice and stir for 1 minute to combine.

  • Serve in wholewheat tortillas with your chosen toppings.

Why it works on GLP-1 medication

High protein supports fullness and muscle maintenance, while fibre-rich vegetables add volume without heaviness. Using minimal oil and yogurt instead of sour cream can also help reduce reflux or nausea.

Health insight

  • Peppers and onions provide fibre and antioxidants that support gut health

  • Protein helps slow glucose absorption from the tortillas

  • Yogurt or Skyr may support gut microbiome balance

Portion guidance

Start with one tortilla, eat slowly, and pause before having more.

If appetite is lower, you could use lettuce cups instead.

Easy swaps

  • Protein: turkey strips, prawns or tofu

  • Extra veg: mushrooms, courgette or spinach

  • Lower appetite option: lettuce cups instead of tortillas

Gentle reminder

Balanced meals that still feel social and enjoyable are often what lead to the best long-term results 🙂
