In a small bowl, combine the ground turkey with dried sage, garlic powder, onion powder, crushed fennel seeds, sea salt, and black pepper to create a sausage seasoning.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the seasoned turkey to the skillet and cook until browned and cooked through, breaking it into small crumbles with a spatula.
Toss the fresh spinach into the skillet and sauté for 1 minute until just wilted.
Lower the heat to medium and pour the egg whites over the turkey mixture, stirring gently until the eggs are set and fluffy.
Warm the whole wheat tortilla in a separate dry pan or microwave for 10 seconds until pliable.
Spread the Greek yogurt across the center of the tortilla as a creamy base.
Top the yogurt with the hot turkey and egg scramble.
Sprinkle the shredded cheddar cheese over the filling so it begins to melt from the residual heat.
Fold in the sides of the tortilla and roll it up tightly to form a secure wrap.
Optional: Place the wrap back in the skillet for 30 seconds per side to create a golden, crispy exterior.
