Season chicken breasts on both sides with 1/8tsp salt, 1/8 tsp each black pepper, cayenne pepper, and cumin. In a large skillet saute chicken in hot oil 3 to 4 minutes on each side, until golden. Remove and slice thin.
Make guacamole by mashing avocado, adding other ingredients, and seasoning to taste with remaining salt, peppers and lime juice.
Lay half the chicken slices on one of the tortillas, cover with half the guacamole, and roll up tortilla. Repeat. Serve with sour cream on the side for dipping.
