Roast some basic veg - carrots, parsnip, potatoes, butternut pumpkin, red onions, with olive oil, S&P, thyme & rosemary if you like 'em, plus some slices of garlic. Put the pimientos in for the last 10 minutes of roasting, toss them all around. Delish! Serve as a stand alone dish, add some fetta cheese for a vegetarian complete dish, maybe even some kalamata olives, or add as a base for some roasted lamb, beef or fried fish even.
Or sautee some onions/eschallots, then add pimientos, heat thru, add some dried ground oregano or whatever suits your fancy, puree and sieve to make a sauce.
Wish I had your problem :)
