Start with unsalted, blanched peanuts. We got ours in bulk.
Pour in about 2-3 tbsp melted margarine (butter or even oil I'm sure would work as well).
Salt and pepper to your liking.
I chopped some dried rosemary and added that also.
Spread evenly on a baking sheet, and bake at 375° F. I had quite a lot and left them in for about 15 minutes. Just check them frequently to make sure they're not burning, and take them out when they've browned nicely.
Ta da! This is about half the batch.
These peanuts tasted great and made the house smell amazing. They appeared to be a hit at our get together, especially with the men. The best part is that you could do this same basic process with almost any type of nut and endless variations of seasonings could be used. Enjoy experimenting, and of course, be aware of any nut allergies before you serve these at a gathering.
