Cheesy Beef Toaster | The Ultimate Grilled Sandwich

Heat a skillet over medium heat and add butter.
Add chopped red onion and sauté for 2 minutes until slightly soft.
Add ground beef, season with salt, pepper, garlic powder, and onion powder, and cook until browned (5-7 minutes).
Stir in Worcestershire sauce, mix well, and remove from heat.
2. Assemble the Sandwich
Spread butter on one side of each bread slice.
On the unbuttered side, layer cheddar cheese, beef filling, and mozzarella cheese.
Top with another slice of bread, buttered side facing out.
3. Toast the Sandwich
Heat a skillet over medium-low heat.
Place the sandwich in the skillet and cook for 2-3 minutes per side, pressing down gently with a spatula, until the bread is golden brown and the cheese is melted.
4. Serve & Enjoy!
Slice in half and serve warm with your favorite dipping sauce (such as ketchup, garlic aioli, or BBQ sauce).
