Heat a large sized skillet over medium heat. Add olive oil to pan. Cook the turkey meat until almost all the way browned. Add the diced onions and bell peppers. Continue cooking until the turkey is fully cooked and the onions are translucent and the bell peppers have softened.
Transfer the cooked turkey, onions and bell peppers to the slow cooker. Next add in the uncooked quinoa, pinto beans, corn, diced tomatoes with green chilies, red enchilada sauce, water, garlic, chili powder and cumin to the slow cooker. Mix everything together well.
Cover the slow cooker and cook on high for 3 hours. When finished, the stew will be very moist, but not soupy. If there is still a lot of liquid after 3 hours, cook for an additional 30 minutes.
Notes
If you are short on time, raw bell pepper and onion can be added directly to the slow cooker, instead of being sautéed with the ground turkey. Either way, the finished product tastes great!
