I wish I knew 100% what is in the Roasted Tomato Sofrito Blend, but what I have found by tasting it paired with a little research is that it's a blend of tomatoes, onion, Canola Oil, Extra Virgin Olive Oil, Dried Garlic, Vinegar, Salt, Sugar, among other secret spices. I've found that by slow roasting grape tomatoes it tastes very similar to that delicious tomato sofrito blend Panera has!
