Fill a pot with 2.5 cups of water and bring to a boil. Once boiling, add rice; reduce heat to a simmer and cook for 20-25 minutes or until the liquid has evaporated.
Meanwhile, spray a large skillet with cooking spray and set to medium heat. Add the ground turkey and cook, breaking the meat with a wooden spoon as you go, for about 5 minutes, or until no longer pink.
Add the water, taco seasoning and tomato paste and stir to combine. Simmer for about 2-3 more minutes, stirring occasionally, until most of the liquid has evaporated.
Add the zucchini and onion and cook, stirring occasionally, until veggies have started to soften, about 5-6 minutes.
Once rice is done, add it to the skillet and mix it in with everything else. Remove from heat.
Sprinkle cheese over top and place a lid on the skillet and let sit until cheese is melted (or if cooking in an oven-safe skillet you can broil for 1-2 minutes until cheesy).
Top with sour cream, cilantro, tortilla chips, salsa, etc. and enjoy!
