Grilled Blue and Cheddar Cheese Sandwiches

This is a recipe that was passed along to me by my grandmother. I have no idea where she got it from, probably a magazine, but I always loved these when I was a kid. She’d make a whole loaf of them and freeze them right in the bread bag  so the only prep was buttering them and grilling them. 

1/3 Cup Mayonaise
2 Teaspoons Worcestershire Sauce
1 Teaspoon Mustard
2 Cups Grated Cheddar Cheese
1/2 Cup Crumbled Blue Cheese
2 Tablespoons Finely Diced Onion
1 Small Can of Mushrooms
1/4 Teaspoon Cayenne Pepper 

Mix the ingredients together, spread on bread, butter the outside and grill on medium-low heat.

I can’t decide whether I love these sandwiches because I love blue cheese or I love blue cheese because I love these sandwiches.
