Spiced chicken strips roasted on a tray with peppers and onions, then wrapped in warm wholemeal tortillas with avocado, lime and Greek yogurt. A homemade spice mix and 40 minutes are all it takes.

Two fajitas have about 47g of protein and 12g of fibre for 583 calories, including the tortillas, avocado and yogurt. That makes it a substantial dinner with a full portion of vegetables.
Why a sheet pan. Restaurant fajitas are usually cooked in plenty of oil on a sizzling griddle. Roasting on two trays at a high heat gives the same charred edges with 2 tbsp of oil for four people, and there is almost no washing up.
Simple swaps that add up. Greek yogurt in place of sour cream gives the same cool tang with far less fat and more protein. Wholemeal tortillas have more fibre than white ones. Making your own spice mix means you control the salt: shop-bought fajita kits are often high in it.
Colourful peppers. Red and yellow peppers are among the richest vegetable sources of vitamin C, and avocado adds fibre and monounsaturated fat.
Not gluten-free as written; use corn tortillas labelled gluten-free if you need to. For another Mexican-style dinner, try the chicken burrito bowl or the vegan sweet potato and black bean tacos.
