Place a skillet over medium heat and wait about a minute. In the meantime, combine the cheese and nuts in a small bowl.
Lightly spray the pan with nonstick spray, then spoon in little mounds of the mixture (about a tablespoon each) and spread them into thin circles with the back of the spoon.
Cook over medium heat until the cheese has melted and the “cracker” seems to have solidified (about 2 minutes), then firmly but gently dislodge with a sturdy metal spatula and flip over to cook on the second side. Cook until golden and crisp, then remove to a plate. Serve at any temperature. (These keep really well).
