While this stuff was absolutely so yummy the way I made it, the next time I make this (which will be very soon), I will do a couple of things differently.  First, I will add more fritos, maybe a bag and a half instead of just one bag.  I wanted more salty with the sweet.  Second, after pouring the peanut butter mixture over the top of the fritos, I will gently toss it, just to cover the fritos more evenly.  Also, I used the regular size fritos, and I think I’ll use the “scoops” size next time.
