- STEP 1
Heat oven to 220C/200C fan/gas 6. Cover a baking tray with parchment. Lay each chicken breast flat on a board, then halve through the middle so you get 2 breast-sized pieces from each.
- STEP 2
Bash 85g of tortillas (see tip, below) into rough crumbs and small flakes, then tip into a shallow bowl with 1 tsp of the chilli powder and some salt. Mix well. Dip each piece of chicken into beaten egg. Mix the remaining egg into the tortilla crumbs. Now dip each chicken piece into the crumbs so you have a patchy crust.
- STEP 3
Roast on the tray for 12 mins until the chicken is cooked through. Meanwhile, cut the avocado and tomatoes into chunks and thinly slice the onion. Whisk the remaining chilli powder and some seasoning into the lime juice, then mix through the avocado, tomatoes and onion. Serve 2 crispy chicken pieces per person with a spoonful of guacamole salad and a handful of the remaining tortillas.
