To a large ziptop bag, add the soy sauce, olive oil, apple cider vinegar, honey, pepper, steak, seal bag, and squish contents around to mix and evenly coat the steak. Place bag in the fridge to marinate for (at least) 15 minutes, or up to 4 hours.
Preheat outdoor grill to medium heat; alternatively preheat an indoor grill pan.
To a wooden skewer, add a piece of steak, pieces of peppers, onion, zucchini, pineapple, and repeat the ingredients until the skewer is full. Repeat with all remaining skewers.
Add the kabobs to a lightly oiled grill, cover, and cook for about 7 minutes for medium rare (145F) and about 8 to 9 minutes for medium (160F) doneness. Turn kabobs occasionally. Exact cooking time will vary on the type of grill, the size, the heat level, how big the pieces of steak are on each kabob, etc. Cook until done to your personal preference.
If desired, season with salt and pepper, and optionally garnish with fresh herbs. Let kabobs rest a few minutes prior to serving. Kabobs are best warm and fresh.
