Heat a large nonstick skillet over medium-high heat.
Add the chopped onion and minced garlic to the hot skillet and cook, stirring, until the garlic is fragrant and the onion softens, about 4 minutes.
Add the ground turkey to the skillet and cook, breaking it up with a wooden spoon, until fully browned, about 10 minutes.
Stir in the frozen corn, drained black beans, and chopped chipotle peppers with their adobo sauce; mix well.
Reduce heat to medium and simmer the mixture for about 10 minutes to blend flavors and heat through.
Warm the tortillas on the stove or in the microwave if desired.
Spoon about 3/4 cup of the turkey mixture into each tortilla and garnish with a dollop of fat-free Greek yogurt, freshly chopped cilantro, and salsa as desired.
