Preheat the oven to 425°F and line a large baking sheet with parchment paper
Toss the bread cubes with 2 tablespoons of olive oil and the garlic salt
Spread the bread evenly on the prepared baking sheet and bake for 10-12 minutes, tossing once halfway until golden brown and crusty. Remove from oven and let cool.
Quickly marinate the shrimp by tossing the shrimp with 1 tablespoon lemon juice, zest, spices, and salt and pepper. Let set 5-10 minutes. When ready to eat, grill the shrimp 2-3 minute per side over a medium flame. Let rest while assembling the salad.
Prepare the basil vinaigrette by placing all vinaigrette ingredients into a food processor and pulsing until the ingredients have emulsified and the basil is finely minced.
To assemble the salad, toss together the kale, sugar snap peas, green onions, peaches, and panzanella croutons. Pour half of the basil vinaigrette over top and toss to coat. Plate the salads and place the cooked shrimp on top. Serve with additional dressing on the side.
