Using 2 tablespoons of the butter, butter one side of all 4 pieces of the Croissant Loaf.
Place 2 pieces of the buttered Croissant Loaf in a skillet that has been heated on medium. Layer 3 pieces of the OKA cheese on each slice of Croissant Loaf. Top with the remaining slices of Croissant Loaf, buttered side up.
Grill the sandwiches until they are golden and toasty, flip and repeat for the top side.
Once the sandwiches are perfectly golden and toasty, remove from the skillet, place on a wire cooling rack, and allow to cool.
Once cooled, use a serrated knife to cut each sandwich into 9 cubed pieces.
Melt the remaining butter in a skillet set on low. Place the grilled cheese cubes into the skillet, taking care to grill the cut side of the cubes.
Using tongs, turn the cubes to lightly grill all 4 sides of the cubes.
Serve immediately as an indulgent topping for soup or even salad. OKA grilled cheese croutons would pair perfectly with a roasted cauliflower soup or a creamy tomato bisque.
