I know Velveeta isn't cheese but it still makes good grilled "cheese product" sandwiches.
This is a recipe my mom got from a one of the Taste of Home/Quick Cooking mags-not sure which one. It's super yummy served with Italian tomato soup to dip it in.
Ultimate Grilled Cheese Sandwich
3 oz cream cheese, softened
½ cup mayonnaise
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
Garlic powder and salt to taste
⅛ tsp seasoned salt
Slices of Italian Bread (can use any kind)
butter or margarine softened
In a mixing bowl, beat cream cheese and mayonnaise until smooth. Stir in cheeses, garlic powder and seasoned salt. Butter the outsides of bread and put them together. Spread cheese mixture on bread and put bottom side on top so that both buttered sides are to the outside. Cook in skillet until golden brown, flip and cook other side until golden brown.
