Flank Steak Sandwich Marinade

Start by mincing the garlic and dicing the onion. Next, grab yourself a large bowl and add in the onions, garlic, wine, soy sauce, olive oil and dried mustard, whisking until combined.

Now that the marinade is made, it’s time to julienne the peppers and slice the red onions. Once done, we can go ahead and get everyone in the tub for some soaking time.

Next, place your flank steak in a deep pan. The aluminum foil pans work great for this. Top with the julienned peppers and sliced onions and then pour the marinade on top. Using a tongs, move the ingredients around so they are coated with the marinade. Cover with foil and place in your refrigerator for 3-6 hours. The more time the flank steak marinates the more tender it will become. You can absolutely do this the night before, however remove the flank steak from the marinade the morning of your party. Although the marinade acts as a meat tenderizer, if you leave the flank steak in too long (say over 12 hours) it will start to break down and become mushy.

Party Time!

This particular recipe comes from way way back and believe it or not, I credit this one to my dad! It had been a rough few years for him as he and my mom divorced and I decided to leave the state for a couple of years. Poor guy.

Shortly after I returned home, my dad started to have his yearly 4th of July parties. He had the set up down to a tee. Everyone in the family had their signature dish that they would bring. My Uncle Tom and Aunt Cathy would bring their famous SPICY CHILI, my in laws (at the time) brought the ever so popular POTATO SALAD WITH BACON and my Yia-Yia would bring her PASTICHIO, GRAPE LEAVES and fan favorite, CHEESE TRIANGLES.

Those were the days when family was healthy, happy and in their prime. My Uncle Jim always had to make a “splash”. Every year we would all wait for him to stand at the edge of the pool and do the Nestea Plunge. The simple things made for lasting memories. Then there was always “friendly” matches of Quoits.

I will hold those parties dear to my heart. Every time I make Marinated Flank Steak Sandwiches that nostalgic feeling comes over me.

Grilling the Flank Steak

Before firing up the grill, remove the flank steak from the refrigerator and let the meat come to room temperature, about 30 minutes or so.

In the meantime, either create a large aluminum foil pouch OR use the aluminum foil pan and place the julienned peppers and sliced onions in the pouch/pan. You’ll want to make sure that you seal it tightly. This will ensure that the veggies will steam.

Moving pepper and onions to a tinfoil pan

Turn the grill on high letting it get nice and hot. Place the peppers and onions on one side of the grill, making sure to lower the heat to medium. Grill the veggies for 20 minutes checking in on them once or twice.

Once the meat has come to room temperature place it on the other side of the grill. You will most likely have to turn the heat down a bit as you don’t want to burn the steak. Cook for 4-5 minutes per side for medium rare or until the internal temperature reaches 130ºF. Remove from grill and tent with foil. Let the flank steak rest for 10 minutes.

Cut the flank steak, against the grain, into thin slices. Place on a large tray along with the veggies. Serve the Marinated Flank Steak Sandwiches on a Kaiser roll and top with a heaping pile of the tender veggies.

As far as condiments go, we keep it simple because the meat is extremely tasty. So with that being said, we like to add some horseradish and some hot sauce and call it a day.

These Marinated Flank Steak Sandwiches are so easy to make and can feed a lot of people with minimal prep and cooking time. I hope you try this recipe at your next summer party.~Christina
