I am looking for healthy (cold) pasta, potato or rice salad dishes that are also "frugal"...What is your favorite yummy dish?
Cold Couscous Salad
Just mix some cooked couscous (buy the couscous in bulk so it's really affordable) with olive oil and balsamic (or red wine) vinegar . . . or even a bottled Italian Dressing. Add chopped vegetables as you like; I use seeded, peeled cucumber, red pepper, cherry tomatoes and green onion. Then I throw in some feta cheese and calamata olives, salt and pepper.
Maybe ingredients like calamata olives and red peppers aren't exactly frugal, but if you can get a couple days' meals for under $10, that's not too bad. I could eat it every day.
