First, make the spice paste; combine the paprika, oregano, thyme, cayenne pepper, salt, garlic and olive oil in a small bowl and set aside
Lay the chicken breasts on a chopping board and cut through each horizontally, being careful not to cut all the way through to the other side; open out the breasts so they resemble butterflies
Rub the spice paste all over the chicken, then put the chicken in a shallow dish, cover and chill for 2-3 hours to marinate
Mix all the salsa ingredients together in a bowl with some seasoning; cover and chill
Take the chicken out of the fridge 15 minutes before you are ready to cook it; heat a griddle pan to medium heat; cook the chicken for 4 minutes each side until cooked through; serve with the salsa
