Zest the lime and set aside.

Reserve half of the lime juice.

In a large skillet, heat over medium heat and add ground turkey.

Dice red bell pepper and Roma tomato into small pieces.

Add the diced vegetables to the skillet with the turkey.

Break up the ground turkey as it cooks.

Cook for approximately 4 minutes.

Add the reserved lime juice, black beans, salt, cumin, chili powder, garlic powder, and sweet chili sauce.

Continue cooking until the turkey is fully cooked through.

This should take about 5 more minutes.

Cut the avocado half into cubes.

Add the lime zest to the sour cream and mix.

To assemble, place lettuce leaves on a plate.

Spoon about 2 heaping tablespoons of the turkey filling onto each lettuce leaf.

Top with avocado cubes and a dollop of the lime-zest sour cream.

Serve immediately and enjoy.
