- Arrange flank steak, peppers, and squash vertically on a cutting board. Carefully skewer approximately 4 skewers through each ingredient, then slice into individual skewers. Repeat with remaining ingredients if necessary. Top each skewer with a pearl onion to cover the sharp end.
- Grill the skewers on a preheated grill set to medium-high heat for about 4-5 minutes per side (until steak is cooked to desired doneness and veggies are nicely charred). Before removing skewers from the grill, brush with Kikkoman® Teriyaki Marinade & Sauce on each side and allow the sauce to cook for the last minute or so of cooking.
- Toss cooked soba noodles with a little vegetable oil and sliced scallions, then top with 2 steak skewers and enjoy.
