Meanwhile, in a small saucepan, combine cheese, evaporated milk, dry mustard and one dash of cayenne pepper. Cook and stir over medium heat until cheese is melted and sauce is smooth. Cover and keep warm.
Place the mixed vegetables into a large mixing bowl. Stir in the minced onion and garlic. Add the egg, milk, flour, baking powder sugar, salt and remaining dash of cayenne pepper. Stir until combined.
