This spice mix would be great with beef strips or mince too. I use French onion soup mix rather than onion and garlic powders as they are ingredients that I don’t have any other use for.
(for 8 tacos, serves 4)

500 grams chicken thighs
1 onion
1 teaspoon vegetable oil
2 cloves garlic
1 tablespoon sweet paprika
1 teaspoon chilli
1 tablespoon cumin
1 teaspoon oregano
1 ½ tablespoons French onion soup powder
¼ teaspoon mild cayenne
½  teaspoon salt
1 teaspoon ground coriander
¼ teaspoon black pepper

8 flour tortillas

½ Lettuce
4 medium Tomato
200 ml Sour cream
100 grams grated Cheese
1 avocado or avocado dip

Mix all the herbs and spices together with the French onion soup powder. Slice the chicken into 5 ml strips and coat all the chicken in the spice mix, you might find it easy to put it all together in a bag hold the end shut tight and give it a shake.

Slice the onion and crush and heat a heavy based pan with the oil. Fry the onion and garlic until tender and add the chicken and cook turning regularly for about 6 minutes or until cooked through.

Slice the lettuce, avocado and tomato and assemble in the middle of the tortilla add the chicken, cheese and sour cream and serve immediately
