Guacamole Grilled Cheese Sandwich Recipe

Mash avocados in a large bowl. Add onion, lime juice, jalapeno, cilantro, garlic, salt, and pepper. Mix until well combined. Stir tomato into the guacamole.

Spread desired amount of guacamole over 2 bread slices. Top each with 2 slices of Havarti cheese. Cover with the remaining 2 slices of bread, then butter the outside.

Heat a skillet to medium-high heat. Cook sandwiches for 2 to 3 minutes until golden brown on the bottom. Flip and cook for 2 to 3 minutes more until the other side is browned.
