Ingredients (makes 4 servings)
1.5 lbs ground beef
8 oz mushrooms, sliced
1 medium onion, thinly sliced
3 garlic cloves, minced
1 tbsp Worcestershire sauce (optional, check for sugar-free)
1 tsp Italian seasoning or steak seasoning
Salt and black pepper to taste

2 tbsp butter or olive oil
Optional add-ins:
Sliced bell peppers
Jalapeños for heat

Instructions
Heat butter or oil in a large skillet over medium-high heat.
Add the ground beef and cook until browned, breaking it up with a spoon. Drain excess fat if needed.
Add sliced onions and mushrooms. Cook for 6–8 minutes until the vegetables are tender and mushrooms are golden.
Stir in minced garlic, Worcestershire sauce (if using), Italian seasoning, salt, and pepper. Cook for 1–2 more minutes until fragrant.
Reduce heat to low. Sprinkle the shredded cheese evenly over the top. Cover and let it melt for 2–4 minutes until bubbly and gooey.
Remove from heat and serve hot — straight from the skillet or spooned into bowls.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until hot and cheese is melty again. This dish also freezes well for up to 2 months.
