Take your favorite grilled cheese sandwich to a new level with basil leaves, tomato slices and two kinds of cheese.
Combine 3 tablespoons Butter with Olive Oil and basil leaves in small bowl; set aside.
To assemble each sandwich, spread 1 side of each bread slice with spread mixture. Layer 1 slice bread, spread-side up, with 1 slice mozzarella cheese, 1/4 tomato slices and 1 slice Cheddar cheese. Top with remaining bread slices, spread-side down. Spread outside of sandwiches with 2 tablespoons Butter with Olive Oil.
Heat 12-inch skillet or griddle on medium heat. Place sandwiches into skillet. Cook, turning once, until cheese is melted and bread is toasted (6 to 8 minutes).
