"A unique chimichurri sauce that is great on everything! What makes it unique? It is a little thicker than the normal chimichurri with tomato and onion pieces. I have used in on fish, flank steak and chicken. I have even mixed it into classic spaghetti sauce recipes."
Toss onion, tomato, garlic, parsley, oregano, paprika, salt, and pepper together until evenly combined. Add olive oil, red wine vinegar, and water; stir well to combine. Refrigerate until flavors are blended, 8 hours to 3 days.
