Try a small amount of sweet chili sauce in omelettes.
I stir fry finely chopped red & yellow peppers, onions, fresh garlic & jalapeno peppers & mushrooms, then add scrambled egg, turn down heat and cook for 5 minutes in a covered pan. Oh always add cooked ground Italian sausage to egg, it is the key ingredient for tasty omelette.
Love Mexican omelets. Chorizo is a good addition too.
