Step 1

Preheat oven to 350°F. Slice bread 1/2 inch thick. Tear into bite-size pieces. Spread in single layer on a baking sheet. Bake 12-15 minutes, turning once, until bread is crisp on the edges, not toasted all the way through. Cool.

Step 2

In a large bowl, whisk together 3 tablespoons olive oil, vinegar, capers, brine and 1/4 teaspoon pepper. Add tomatoes, basil and red onion. (Mixture can be made ahead to this point).

Step 3

Preheat grill to high heat. Drizzle remaining 1 tablespoon olive oil over chicken tenders. Combine garlic powder, salt and remaining 1/4 teaspoon pepper in a small bowl. Sprinkle over tenders and rub together to evenly coat with seasoning.

Step 4

Grill tenders 2-3 minutes on each side until grill-marked and cooked through (170°F).

Step 5

Gently mix bread into tomato mixture. Slice chicken into smaller pieces if desired and fold into bread salad with feta cheese. Serve immediately for a crunchy bread salad, or, let stand until bread is softened.
