Toast the turkey slices in a skillet over medium heat for about 5-7 minutes on each side until golden brown. Set aside to cool.
In the same skillet, toast the pecans for about 3-5 minutes until fragrant and lightly browned. Chop some for added texture.
Combine balsamic vinegar and honey or brown sugar in a small saucepan over medium heat. Simmer for about 10 minutes until it thickens slightly. Allow to cool.
Rinse strawberries, remove tops, and slice. Rinse blackberries and set aside.
In a large mixing bowl, add baby spinach as the base. Layer with sliced strawberries, whole blackberries, toasted turkey, crumbled feta, and pecans.
Drizzle with balsamic glaze just before serving and toss gently to combine.
Serve immediately for maximum freshness and crunch.
