Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes if dry or according to package directions if fresh. Drain pasta reserving 1 cup of the pasta cooking water.
Preheat a grill to high. Whisk the olive oil, vinegar, herbs, honey, 3/4 teaspoon salt and a few grinds of pepper in a medium bowl. Remove 2 tablespoons of the vinaigrette to a large bowl; set aside. Add the cucumber, tomatoes, red onion, feta and olives to the bowl with the remaining vinaigrette; toss to coat.
Season chops with salt and pepper. Heat the extra-virgin olive oil in large skillet over medium-high heat. Add the crushed garlic and stir it around to flavor the oil. Add in the chops and caramelize on both sides, 2 to 3 minutes per side. Remove the chops to a plate and reserve. Stir in the fennel seed, onions, red pepper flakes, and oregano. Reduce the heat and cook for 7 to 8 minutes.
Preheat the broiler. Whisk the yogurt, 2 1/2 tablespoons olive oil, the lemon juice, garlic, 1/4 teaspoon salt and the cayenne in a large bowl. Add the kale and toss to coat; set aside at room temperature while you prepare the shrimp.
Toss the shrimp with the remaining 1/2 tablespoon olive oil on a baking sheet. Broil until just cooked through, 4 to 5 minutes; let cool slightly.
Add the shrimp, chickpeas, tomatoes and red onion to the bowl with the kale; toss to coat. Stack the pitas on a plate and warm in the microwave, about 30 seconds. Fill with the shrimp-kale mixture.
