These Grilled Steak Kabobs are made with a tender and juicy sirloin steak and marinated in a zesty marinade. Fresh vegetables perfectly charred. Topped with a flavorful buttery chimichurri sauce. You will want to make these all summer long!
Cube sirloin steak into 2-3 inch cubes. In a small mixing bowl, whisk together ingredients for marinade; coconut aminos, red wine vinegar, olive oil, pink sea salt, black pepper, minced garlic clove, and lemon juice. Place cubed steak in a zipper bag and pour in marinade. Zip bag and shake steak making sure it gets well coated with marinade. Refrigerate for at least one hour. Preferably, overnight.
Start assembling your kabobs; I like to start with a vegetable and follow with a cube of steak. Then continue with a different veggie and another piece of steak. Continue assembling alternating a different vegetable with a steak. I like to use 4-5 cubes of steak per skewer with a different veggie in between each piece. Reserve the leftover juices from the steak marinade.
Preheat grill on medium-high heat.
Once skewers are assembled and grill is preheated, place kabobs on grill. Brush some of the leftover marinade over each kabob while on the grill. Close grill and grill for 3-4 minutes. Slightly turn kabobs over to the side and rub more marinade over them. Grill again for another 3-4 minutes. Continue this pattern grilling the kabobs for a total of 12 minutes. Turning them 2-3 times to cook on every side and rubbing more marinade each time.
Grilling the kabobs for 12 minutes will result in medium-rare steak. If you want your steak with no pink add 2-3 minutes to the total cooking time. If you want it more on the red side, cook for 2-3 minutes less.
Remove kabobs from the grill and set aside to allow them to slightly cool down a bit. In the meantime, melt butter making sure it's completely melted. Add the rest of ingredients for chimichurri sauce to a food processor. Blend on high and slowly pour butter into food processor as ingredients are being blended. Continue blending for 40-60 seconds. Pour sauce into a serving bowl or jar.
Serve kabobs along with buttery chimichurri sauce. Enjoy!
