 Tacos are always a favorite on our table and this wholesome, nutritious taco seasoning simmer sauce has a wonderful blend of spices and herbs making it the centerpiece of this casserole. We used a packet of Simply Organic-Southwest Taco Simmer Sauce to create this delicious meatless casserole.   This sauce is perfect for simmering meat in and gives it a spicy southwest spin. We definitely recommend using this sauce for a quick and easy meat-based meal, however for this recipe, we went ‘outside the box’ of the simmer sauce instructions to show the versatility of the sauce.  The Simmer Sauce flavors the quinoa superbly!

We combined quinoa with the simmer sauce and all those wonderful flavors in the sauce were absorbed into the quinoa grains.  Quinoa is a favorite ingredient in our arsenal for quick meals.  It is an ancient, high-protein, gluten-free grain.  One cup of cooked quinoa provides eight grams of protein and five grams of fiber.

We added nutritious black beans, corn and a generous measured blend of mozzarella and cheddar cheese to the top, then it was baked briefly to heat through and get that cheese all melty and gooey.

Salty Cotija cheese and chopped fresh cilantro was sprinkled on top of the casserole and it was served with avocado slices, salsa, sour cream and fresh lime wedges.
