Here is my recipe for Pecan, Panko, and Butter Crust Topping;
(Simple, Simple, Very Simple)
1/4 cup salted butter
1 cup Panko bread crumbs
1/4 -1/2 cup broken pecans
First, melt the butter in a skillet.
Add the Panko and broken pecans.
Stir well and allow to get hot for 1 minute.
Then sprinkle the topping on your favorite veggie casserole, macaroni and cheese, tuna casserole, or steamed veggies. Bake casserole as usual, but make sure the pecans do not burn.
Give it a try.
(Next time I try this crust, I'll add Italian herbs/spices.)
