Ingredients

2 lbs ground beef
1 cup white onion, diced

1 cup tomatoes, diced
1 tablespoon olive oil or avocado oil

2 cups iceberg lettuce, chopped
1/4 cup black olives, sliced

3 to 4 cups sharp cheddar cheese (or cheese of choice)
1/2 tablespoon paprika
1/2 tablespoon cumin

1/2 tablespoon chili powder
1 teaspoon cayenne pepper
1 teaspoon salt

Instructions

Step 1: Heat olive oil in a sauté pan over medium heat. Add ground beef and diced onions, cooking until the beef is browned and the onions are soft.
Step 2: Drain excess grease if needed, but leave some to keep the mixture moist.
Step 3: In a small bowl, combine cumin, paprika, cayenne pepper, salt, and chili powder. Sprinkle this seasoning mix over the beef and stir well to coat evenly.

Step 4: Chop the tomatoes and lettuce while the beef simmers. Transfer the seasoned beef to a casserole dish and evenly spread it out. Top with sharp cheddar cheese.
Step 5: Broil on high for about 5 minutes or until the cheese is melted and bubbly. Remove from the oven and garnish with chopped lettuce, diced tomatoes, and sliced black olives before serving.

Tips & Variations

Use Monterey Jack or pepper jack cheese for a different flavor profile.

Add a dollop of sour cream or guacamole on top for extra creaminess.
Swap ground beef for ground turkey or chicken for a leaner option.
Include diced jalapeños if you like a bit more heat.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. For best texture, add fresh lettuce and tomatoes after reheating.
