I love casseroles. They are classic comfort food for me. In this Tex-Mex casserole I paired whole grain elbow macaroni with cauliflower rice, taco seasoned ground turkey, corn, onion, red bell pepper, queso and shredded cheese. The elbow macaroni stands out while the cauliflower rice vanishes into the background. The ground turkey provides a satisfying hit of protein and the cheese adds that ooey gooey goodness.
I went for creaminess in this recipe but for those who like their casseroles more saucy, you can easily add your favorite taco sauce or a can of RO-TEL to the mix. This Tex-Mex casserole is hearty and satisfying. For lunch you can pair it with a warmed tortilla and some fruit. As a main dinner course, you can serve it with a side salad, refried beans, roasted veggies, a slice of cornbread, homemade tortilla chips and some salsa – the possibilities are endless.
The hubby is a cardiac patient so we limit extra toppings when eating this casserole. If you do not have restrictions or you have calories or points to spare, you can top it with light sour cream, slices of avocado or guacamole or any other topping that pairs well with tacos.
This casserole is a great take along to potluck dinners, tailgate parties or game day eats. And best of all, kids like it too.

Instructions

- Chop the required amount of onion and red bell pepper and place it on a paper plate or microwaveable plate. Microwave on high for 60-90 sec until the veggies are tender. Set aside.
- Place the lean ground turkey in a skillet. Use a meat masher or wooden spoon to break up the ground turkey into crumbles. Add about ⅓ c of water to the skillet to facilitate the cooking process.
- When the ground turkey is cooked, transfer it to a colander over the sink to drain away excess water and fat. Rinse the ground turkey with cold water to further rinse away any remaining fat.
- Add the drained ground turkey back to the skillet along with the cooked onion and red pepper, garlic powder, chili powder, ground cumin, ground coriander, paprika, black pepper, and ¾ c of water to the skillet. Stir to mix all the ingredients and spices together. Cook over medium heat until most of the water is evaporated. Remove from the heat and set aside.
