Preheat oven to 350 degrees.In a medium bowl, beat the eggs and mix in ¼ cup cheese, cilantro and olive oil then set aside.In a 10 inch, *OVEN SAFE, skillet, melt the butter then add the sliced onions and peppers.Sprinkle salt and pepper onto peppers and onions cooking.Cook onions and peppers until soft and cooked down (about 5-6 minutes).Add the egg mixture and spread evenly.Carefully lay the jalapenos across the top of the mixture as if you are covering pizza with pepperoni.Cook the mixture until the eggs start to solidify around the edges (about 1 minute).Take the eggs off of heat, coat with remaining cheese and then layer of the crushed tortilla chips.Place skillet in oven and cook for 10 minutes.Remove from oven, cover with sliced avocado and allow to cool.Slide frittata out from skillet onto cutting board and cut like a pizza.Serve with salsa.
