This is a straightforward salsa that checks most boxes for a Charlotte weeknight: grapes and green onions are standard at any supermarket, and the other ingredients—garlic, cilantro, vinegar, and salt—are pantry staples. Anaheim chilies are mild and seasonal but show up reliably at Harris Teeter and Kroger through fall; if you can't find them fresh, a substitute poblano works fine. At roughly 40 cents a serving for fresh produce, it's genuinely cheap, and the stated 15 minutes is honest—mostly dicing. The real caveat is yield: 16 servings means this is a potluck dish or condiment warmed over several days, not a weeknight side for four, so budget for it to live in the fridge and reheat unevenly. The flavor is bright and unusual, but the texture won't hold once dressed, so make it same-day if you want snap.
