Stir together vinegar, honey, garlic, and mustard in a big mixing bowl. Sprinkle in some salt and pepper to season it up.

Toss the steak pieces into the marinade, making sure they're coated. Pop a cover on the bowl and stick it in the fridge for at least 20 minutes or even overnight.

Mix the tomatoes, olive oil, and rosemary in a separate bowl. Put it aside for now.

Put small potatoes in a big pot, cover them with water so it's about an inch above them. Boil until they're just soft enough to poke with a fork, about 8-10 minutes. Drain the water, then set the potatoes aside.

Slide the ingredients onto the skewers. Start with a potato, then steak, then a tomato. Keep going two more times, and finish it off with another potato at the end.

Oil the grill grates, then lay the skewers on. Cook for about 5 minutes on each side, for a total of 10 minutes. Make sure you don't overdo it or dry out the steak.
