Mix the paprika, cumin, chilli powder, oregano, garlic powder, 1 tablespoon olive oil and lime juice together. Rub it into the chicken. You can add a bit of salt but not too much as the stock may be enough
Heat 2 tablespoons olive oil in a pan. Sear the chicken breasts for about 3 minutes on each side until nicely browned. Doesn't have to be fully cooked on the inside as it can cook further in the sauce
Remove the chicken, shred it and set aside
Add the tomato paste and hot sauce to the same pan and cook for a few seconds. Add the chicken stock and heat through
If your sauce is not thick enough you can turn up the heat and reduce it a little more at this stage
Place the shredded chicken into the sauce and allow it to heat through.
Turn on the grill function of your oven
Place half the tortilla chips in an ovenproof dish or a baking pan. Spoon the chicken on top. Add the grated cheese with some jalapeno. Scatter the other half of the tortilla chips along the edges
Pop the tray into the oven just until the cheese melts, about 5-7 minutes. Garnish with coriander
Serve with sour cream and guacamole if you prefer
