Heat up a large skillet over medium-high heat then add a little bit of cooking oil to the skillet.
Once the oil is hot, add the bell peppers and onions. Cook until softened and translucent, about 3-4 minutes.
1 cup diced red bell peppers, ⅔ cup diced white onion
Next, add the broccoli florets and a splash of water then cover the skillet with a lid to lightly steam the broccoli. Once the broccoli is cooked to your desired doneness, add the minced garlic and stir to incorporate.
2 cups broccoli florets, 3 cloves garlic
Add the ground turkey to the skillet and using a meat chopper or spatula/wooden spoon, break it into smaller pieces.
1 pound lean ground turkey
Add the teriyaki sauce on top and reduce heat to a medium low. Stir to combine and gently allow to simmer for 5-7 minutes then remove from heat.
