Place seasoning in a small bowl and mix. Set aside.
Slice the chicken in half (horizontally). Transfer chicken to a large bowl and coat with 1 ½ tbsp olive oil. Sprinkle the seasoning onto the chicken and toss to coat.
Heat a large pan and add the remaining 1 ½ tbsp olive oil. Fry the chicken for about 2 mins on each side (depending on the size of the chicken). Transfer the chicken onto a plate and rest for 3 mins. Chop and set aside.
Stir-fry the onion and garlic in the same pan. Add the capsicum and cook for 2 mins or until the onion becomes translucent.
Add the refried beans, then pour the water carefully. Stir until the mixture comes together. Add the chopped chicken. Stir and cook for another 2-3 mins or until the liquid has reduced slightly. Remove from heat and allow to cool for 5 minutes or so.
If using store-bought tortillas, warm them first in the microwave before adding the fillings. If using freshly-cooked homemade tortillas, use them straight away.
Lay down a tortilla and spoon the rice on top, add chicken, corn, cheese, coriander (or other preferred fillings). Fold it up starting from the edge nearest you, then close both ends and finish folding it up.
