In a medium bowl, combine olive oil, garlic powder, onion powder, black pepper, and your table blend seasoning. Whisk together until well blended.

Add the cubed flat iron steak and sliced pre-cooked sausage to the marinade, covering with plastic wrap. Marinate for at least 30 minutes at room temperature.

Wash and cut the fresh corn, chop the red bell pepper, and slice the purple onion. Microwave the Yukon Gold potatoes until slightly soft.

Assemble the kabobs by threading marinated steak, sausage, corn, bell pepper, onion, and potato onto skewers, repeating until filled.

Preheat the grill to medium-high heat, oil the grates, and grill the kabobs for about 10-12 minutes, turning occasionally until cooked to your liking.

Remove the kabobs from the grill and let rest for a few minutes before serving warm.
