Generous spray of olive oil
Salt, Pepper, Cayenne, Cumin, Paprika.
Make sure that the beans are totally dry by spreading them out over a paper towel and letting it absorb some moisture.
I usually do this twice.
Keep it light on the cayenne if you're not a fan of spice.
Bake at 400 degrees, agitating every now and then for a crisp. I think that a toaster oven is the best place for this since the heat source is closer to the peas.
Still they are wildly filling and full of great nutrients, so I think it's probably OK.
