Ingredients

1 pound Lean Ground Beef
2 cups Bisquick Baking Mix
1/2 cup Water
3/4 cup Green Bell Pepper; Chopped
2 large Tomatoes; Thinly Sliced
1/4 cup Cheddar Cheese; Shredded
1 cup Dairy Sour Cream
2/3 cup Mayonnaise Or Salad Dressing
2 tablespoons Onion; Finely Chopped
to taste Salt & Pepper
1/2 teaspoon Paprika; Optional

Directions

1
Preheat the oven to 375 degrees F (191C).
2
Cook the ground beef in a large skillet over medium heat until browned, stirring occasionally.
3
Drain off any excess fat from the beef and transfer it to a bowl.
4
Season the cooked beef with salt and pepper to taste.
5
In a small bowl, mix together the shredded cheddar cheese, sour cream, mayonnaise, and finely chopped onion. Set aside.
6
In a medium bowl, stir the Bisquick baking mix and water together until a soft dough forms.
7
Grease a 13x9x2-inch baking pan. Using floured fingers, pat the dough evenly into the bottom of the pan, pressing it up the sides by about 1/2 inch to form a crust.
8
Spread the seasoned beef evenly over the dough base.
9
Layer the sliced tomatoes and chopped green bell pepper on top of the beef.
10
Spoon the cheese and sour cream mixture evenly over the vegetables and meat.
11
Sprinkle with paprika, if desired.
12
Bake uncovered for 25 to 30 minutes, or until the edges of the dough are light brown and the topping is bubbly.
13
Allow the casserole to cool for 5 minutes before cutting into squares and serving.

Note

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through.

Substitutions: You can use taco seasoning instead of plain salt and pepper for a more authentic Mexican flavor. Rotisserie chicken can be used in place of ground beef for a lighter option.

Tip: For a crispier crust, bake for an additional 2-3 minutes after the topping is set. Ensure the tomatoes are sliced thinly to prevent excess moisture from making the crust soggy.
