In your large skillet or Dutch oven, heat a drizzle of olive oil over medium heat. Add the diced yellow onion and green bell pepper. Sauté for about 3-4 minutes until they begin to soften. Stir in the minced garlic and cook for another minute until fragrant.
Next, add the ground turkey breast to the skillet. Use your wooden spoon to break it up as it cooks. Cook until the turkey is browned and fully cooked through, about 5-7 minutes.
Once the turkey is cooked, add in the Worcestershire sauce, chili powder, and red pepper flakes (if using). Stir to combine.
Add the canned tomato paste to the skillet. Mix well to combine the paste with the turkey and veggies.
Pour in the 1/2 cup of water. This will help to create a saucy texture. Bring the mixture to a simmer, then reduce the heat to low. Allow it to cook for an additional 5-10 minutes, stirring occasionally.
Once the mixture has thickened to your liking, remove it from the heat. Serve your One-Pot Skinny Sloppy Joes on whole grain buns or over a bed of greens for a lighter option. Enjoy!
