In a large bowl, toss tomatoes, zucchini, onion, olive oil, and salt and pepper to taste. Set aside.
Prepare a grill to medium-high heat and lightly oil the grate. Season pork with seasoned salt and grill until internal temperature reaches 145 degrees F, about 4 1/2 minutes per side.
Place the vegetables in a grill basket and grill, turning or tossing occasionally, until crisp-tender and lightly charred, 8 to 10 minutes. Remove chops from grill and let rest 3 minutes. Remove vegetables and cover to keep warm while chops rest.
Serve the chops topped with the grilled vegetables.
