Tofu-veggie kebabs with peanut-sriracha sauce

Soak eight 10-in bamboo skewers in a shallow dish of water for at least 20 minutes (or use metal skewers).

Bring a large saucepan of water to a boil over high heat. Add salt and radishes to pan; cook 5 minutes. Add broccoli; cook 1 minute more. Drain in a colander; run vegetables under cold water until cool to the touch. Drain well; blot with paper towels.

Blot tofu blocks dry with paper towels; cut each block into 12 even cubes.

To make sauce, stir powdered peanut butter and water together in a medium bowl to form a smooth, loose paste. Add ketchup, miso, lime juice, soy sauce, Sriracha and oil; stir to combine.

To make kebabs, thread 2 radish halves, 2 broccoli florets and 3 tofu cubes on each skewer.

Heat a grill to medium-high heat. Off heat, brush kebabs with sauce on one side and lightly coat with cooking spray. Place on grill, sauce side down; cook 2-3 minutes. Brush other side with sauce; flip and cook 2-3 minutes more.

Remove from grill and brush with extra sauce; sprinkle with sesame seeds before serving. Serve any additional sauce on the side for dipping.
