GF Topping for Green Bean Casserole

Yes, this is my own recipe. My daughter was my taster and we developed it in a day, trying 3 different approaches in the same pan. Others put Funyuns, and that is a fine approach, but it didn't work for us. We wanted something that was satisfyingly similar to the "real thing." This is what we came up with.

Gluten Free Green Bean Casserole Topping

1 C 4C Gluten Free Bread Crumbs
1/2 medium onion, sliced
Salt

3-way Experiment
Upper-left: potato chips + thick slice of fresh onion
Lower-left: breadcrumbs + thick slice of fresh onion
Right: Funyuns

Garlic powder
Onion powder (if needed)
Enough potato chips to make a dry crumb

Place all ingredients in a food processor, until all mixed up. Toast in the oven. I used my toaster oven, for this, because of the timer and lower heat. Toasting is optional, but if you choose not to toast, store in the refrigerator until ready for use.

For the casserole itself:

2 cans Progresso Cream of Mushroom soup
4 cans green beans
1/4 cup cornstarch thickener
Salt and pepper to taste
1/3 of the topping mixed in, if you wish
