Trim steak and cut into strips about 4-6" long and 1/2" thick.
Whisk together marinade ingredients in a large mixing bowl. Place steak strips into marinade, making sure to fully coat meat. Allow to rest in fridge for 10-15 minutes for meat to absorb the flavor.
While steak marinates, chop pineapple into cubes, about 1" square. Wash and dry grape tomatoes.
Spear steak strips lengthwise onto kabob skewers. Follow with a grape tomato and pineapple cube.
Grill for 8-12 minutes, flipping skewers halfway through.
