 Step by Step Instructions

 STEP 1: 

To make this casserole, I started by dumping a pound of lean ground beef into a large skillet over medium-high heat and breaking it apart.

I added some diced onions to the pan with the ground beef as it was cooking.

 STEP 2: 

I stirred well and continued cooking until the ground beef was fully browned.

 STEP 3: 

Then I added some corn and black bean salsa, Heinz chili sauce, taco seasoning, salt, pepper, garlic powder and onion powder to the pan.

I stirred until all of the ground beef was coated in the sauce.

 STEP 4: 

Then I added some chopped green onions to the pan.

I stirred well again and turned off the heat.

 STEP 5: 

I spread 12 slices of bread with margarine.

I cut all of the slices of bread in half.

 STEP 6: 

Then I placed half of the bread slices, margarine side down, in a greased 9 x 13 inch baking dish.

 STEP 7: 

I sprinkled some shredded mozzarella and cheddar cheese on top of the bread.

 STEP 8: 

Then I spooned the ground beef mixture on top of the cheese and spread it out evenly.

 STEP 9: 

I sprinkled some more shredded cheese on top of the meat.

 STEP 10: 

Then I placed the remaining bread slices, margarine side up, on top of the cheese.

 STEP 11: 

I placed the baking dish in the oven and baked the casserole until the top bread slices were golden brown.

Then I removed the casserole from the oven and served it immediately.

This cheesy ground beef casserole has a bit of a kick from the taco seasoning but is not overly spicy.

The seasoned ground beef pairs perfectly with gooey melted cheese and buttery toasted bread.

It’s a cheesy, taco-y masterpiece that deserves a spot on your dinner table.
