Dice all of the onion, peppers and add to a hot saute pan with butter. Saute until tender. Once the vegetables are soft, add the taco seasoning, cream cheese, sour cream, garlic, Frank’s hot sauce, lime juice and stir. Add the cheese, canned corn, feta and stir. Simmer until warm and garnish with cilantro. Serve with tortilla chips. Or, you can pour the dip into a 9x13 pan and bake at 350 for 15-20 minutes, or until bubbly and then serve warm.
