Salsa criolla is the onion-based condiment served alongside many Peruvian and Argentinian dishes. Next to thinly sliced onions, it can incorporate a huge variety of ingredients such as bell peppers, avocados, jalapeños, tomatoes, and generous amounts of freshly chopped parsley and cilantro.
Usually seasoned with salt, vinegar, and lime juice, salsa criolla is versatile, easy to prepare, and should always be served fresh. It is mostly enjoyed as a complement to grilled meat, sandwiches, rice, and popular Peruvian ceviche dishes.
