Cook the veggies. In the same skillet, sauté the green peppers and onion until softened.
Assemble the casserole. Spread the seasoned, cooked meat over the Crescent Roll crust followed by the Rotel. Next, layer in the softened bell pepper and onions followed by ¼ cup of the jalapenos.
Add the creamy topping. Stir together the sour cream, mayonnaise, cream cheese, and then fold in 1 cup of shredded cheddar cheese. Spread the mixture over the casserole and top with the remaining 2 cups of cheddar cheese and ¼ cup of jalapenos.
