Easy Grilled Steak Sliders

Prep and Cook

• 1
  Place the balsamic vinegar in a small saucepan and bring it to boil. Reduce the heat to medium and cook until the vinegar has reduced and thickened to the consistency of maple syrup, about 20 minutes.
• 2
  Heat your grill or pan. Oil both sides of the steak and liberally season with salt and pepper. Cook until you reach the desired done-ness.
• 3
  Remove the steak from the heat and allow it to rest for 10 minutes to keep the juices inside and the meat moist.
• 4
  Slice the steak against the grain into thin strips.
• 5
  To assemble the sandwiches: Combine the Dijon and mayonnaise and mix well. Slice the buns in half and spread the Dijonnaise mixture on both sides. Top the bottom bun with a few leaves of spinach, some steak and a piece of cheese. Cover with the remaining half of bun and repeat with the rest of the ingredients.
• 6
  Skewer the sandwiches with a toothpick and serve.
