This easy, cheesy dip is made in ONE skillet and so much better than store bought cheese dip. Serve the dip warm, right out of the oven, with tortilla chips!
In a 10-inch cast iron skillet, toss together the tomatoes, onion, jalapeno, red pepper, salt, and black pepper. Layer the cheeses on top and bake until the cheeses are melted and bubbling about 10-13 minutes.
Remove the skillet from the oven and sprinkle with cilantro, a squeeze of fresh lime juice, and avocado. Serve immediately with chips.
