Prepare the Marinade and Chicken

1. Make the Marinade: In a bowl, whisk together olive oil, lemon juice, garlic, paprika, oregano, salt, and pepper.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over them, ensuring they are well-coated. Let it marinate for at least 20 minutes (or up to 4 hours for deeper flavor).
3. Preheat the Grill: Heat your grill or grill pan to medium-high heat.

Grill the Chicken

1. Cook the Chicken: Grill the chicken breasts for 6-8 minutes per side, or until the internal temperature reaches 165°F (75°C).
2. Let it Rest: Remove the chicken from the grill and let it rest for 5 minutes before slicing into thin strips.

Prepare the Salad

1. Assemble the Greens: In a large bowl or platter, spread the mixed greens as the base.
2. Add the Veggies: Scatter the cherry tomatoes, cucumber slices, and red onion on top of the greens.
3. Add Protein and Toppings: Arrange the grilled chicken slices on top and sprinkle with crumbled feta and almonds.
4. Add Avocado (Optional): Place slices of avocado for an extra creamy touch.

Make the Dressing

1. Combine Ingredients: In a small jar, combine olive oil, balsamic vinegar, Dijon mustard, honey, garlic powder, salt, and pepper. Shake well until emulsified.
2. Dress the Salad: Drizzle the dressing over the salad just before serving.
