If using freshly cooked turkey breast, season it lightly with salt, black pepper, garlic powder, and a drizzle of olive oil. Bake at 400°F (200°C) for 20–25 minutes, air fry at 380°F (193°C) for 15–18 minutes, or cook in a skillet over medium heat for about 5–7 minutes per side until the internal temperature reaches 165°F (74°C). Let the turkey rest for 5–10 minutes before slicing into thin strips or bite-sized pieces.
Wash the cucumber, cherry tomatoes, bell pepper, fresh herbs, and berries thoroughly. Pat everything completely dry using paper towels or a clean kitchen towel to remove excess moisture. Slice the cucumber into rounds or sticks, halve the cherry tomatoes, slice the bell pepper into strips, and chop the herbs if using.
Place the cottage cheese into a small mixing bowl. Stir in the chopped herbs and everything bagel seasoning if desired. Add a pinch of garlic powder, freshly cracked black pepper, or a squeeze of lemon juice for extra flavor, then mix until well combined.
Measure the almonds into a small reusable container or separate compartment to keep them crunchy until you're ready to eat.
Arrange the sliced turkey neatly into one section of a divided meal-prep container. Spoon the seasoned cottage cheese into another compartment, then fill the remaining sections with the sliced cucumbers, cherry tomatoes, bell peppers, mixed berries, and almonds.
Add optional extras such as hard-boiled eggs, avocado slices, cheese cubes, olives, or pickles if you'd like to customize the lunch box or increase the protein content.
Seal the container tightly with a secure lid and refrigerate for at least 30 minutes before serving. Chilling helps keep the ingredients crisp and allows the flavors in the seasoned cottage cheese to develop.
Serve the lunch box cold directly from the refrigerator. Squeeze fresh lemon over the vegetables or sprinkle a little extra everything bagel seasoning onto the cottage cheese just before eating for an extra burst of flavor.
