So I have experimented on GF bread crumbs without much success. I was given a tip to use toasted waffles, and here's the results! They were great!!!
Just toast 2 Van's waffles, throw 'em in your food processor and grind for a few seconds. Then pour them into a hot pan of melted butter (about 2 tbsp) and let them fry for a couple minutes. Then top your fave dish w/ them and bake. I made tuna noodle casserole for lunch today (first pic), and loved the flavor and crunch the crumbs added!
Threw the rest in the freezer, gonna see how they do second time around. :D
