Thaw and cook the frozen meatballs in the oven until they're warmed through.

While they're cooking, combined the Trader Joe's Jalapeño Sauce with an equal part of ranch dressing in a bowl. Stir together and taste; for a milder sauce add more ranch dressing, for a spicier version add more jalapeño sauce.

Toss the warmed meatballs with the Jalapeño-ranch sauce, and garnish with fresh cilantro and jalapeño slices. Serve immediately.
