Mix the 1 1/2 cups Parmigiano Reggiano cheese and 2/3 cups almonds together in a bowl. Set aside.
Heat a non-stick 8 or 10-inch skillet over medium heat.
Scoop 1/4 cup amounts of the mixture into the pan and flatten with a wooden spoon into a 3-inch round. Cook two or three at one time, spacing them in the pan so the edges do not touch.
Cook like a pancake. When the cheese begins to melt at the edges and turn light brown. flip the wafer over and brown the other side. They should look golden brown.
Transfer to a cooling rack.
