In a medium bowl, whisk together the olive oil, red wine vinegar, cumin, salt, and black pepper. Add diced onion. Taste it, it should be slightly sharp and well-seasoned.
Add the drained beans, corn, and parsley and gently toss to coat. Be careful here; you want them intact, not mashed.
Lastly, add chopped red pepper fillets, mix once again gently, cover, and let the salad marinate for at least 30 min before serving or overnight. Stir once or twice in the meantime.
