In a large bowl, mix together all of the ingredients.
To prepare the 9×13 pan, line it with parchment paper or aluminum foil and spray it with cooking spray. Press the nut mixture into the bottom of the pan.
Bake for 16-18 minutes. Allow the bars to cool for 5 minutes, then pull on the wax paper to remove them from the pan. Use a pizza cutter to slice the bars into rectangles of the size you’d like.
Notes
You can use a mixture of whatever kind of nuts you’d like. We’ve used cashews before, too.
I normally use egg white that come in a carton instead of separating the eggs and having a bunch of yolks left over.
