Step 1

Preheat an oven to 350 degrees Fahrenheit and spray a 9X13 baking pan with a non-stick cooking spray.

Step 2

Place the large biscuits into the bottom of the pan in a single layer on the bottom of the pan and halfway up the sides of the pan.  Make sure to press the biscuits together to form a single layer.

Step 3

Bake the biscuit layer for 12-15 minutes until the dough is lightly browned.  Remove from the oven but leave the oven on.

Step 4

Brown the ground beef in a large skillet over medium high heat.  Drain off any excess grease.

Step 5

Stir in the taco seasoning, water, diced onions and diced red bell pepper.

Step 6

Bring the mixture to a low simmer and cook, covered, for 8-10 minutes until the onions and peppers are soft.

Step 7

Then pour the beef mixture on top of the biscuit layer in the baking pan.

Step 8

Spread the diced tomatoes with green chiles over the beef layer.

Step 9

In a separate bowl, stir together the sour cream, mayonnaise and half of the shredded cheese.  Spread this mixture on top of the tomatoes in the baking pan.

Step 10

Top with the remaining shredded cheese. Bake until the cheese is bubbling and beginning to brown slightly (20-25 minutes).

Step 11

Let the casserole sit for 10-15 minutes.  Then it’s ready to slice, serve and enjoy!
