This is my take on a recipe I scribbled down a long time ago from a website. I like to change things and make them weird. My apologizes.
Blend all ingredients except the bread. Pour into a saucepan over medium heat until it comes to a mild boil then reduce to medium-low heat stirring the entire time. When mixture is thick and smooth, remove from heat.
Cover 2 slices of bread with cheese sauce. Put the other 2 on top of them. You can coat each side with margarine for a crispier sandwich.
Coat grill with a small bit of margarine, veggie oil or non-stick spray. Heat grill and then place sandwichs on them flipping once until each side is golden brown. serve. enjoy.
