Cheesy Beef and Corn Grilled Sandwich

Cook the Beef: In a skillet over medium heat, cook the ground beef until browned. Drain any excess fat. Season with salt, pepper, and garlic powder.
Toast the Bread: Butter one side of each slice of bread. Heat a pan or skillet over medium-low heat and place the buttered side down. Toast until golden brown and crispy.
Assemble the Sandwich: On one slice of toasted bread (buttered side up), layer half of the cooked ground beef, some mozzarella cheese, cheddar cheese, and a few spoonfuls of corn. Place the second slice of bread on top, buttered side up.
