Tri Tip and Caramelized Onion Sandwiches with Mustard Aioli Directions

  1. Place steaks in a resealable plastic bag. Combine marinade ingredients and pour over steaks. Make sure to work marinade well into the meat. Seal the bag and place it in the refrigerator for 2 hours.
  2. Preheat the grill to medium-high heat. While the grill is heating up, slice the onion and heat olive oil in a large skillet on the stove. Add onion, salt and black pepper. Allow onion to cook on high for 2 minutes, reduce heat to medium-low, and cook for 5 minutes, turning often.
  3. Add wine and Worcestershire sauce and cook for 2-3 minutes. Add stock, reduce heat to low, and cook for 15 minutes.
  4. Place steaks on the grill and cook for 10 minutes, turning often. Steaks should cook quickly since they are relatively small and thin. If they are thicker, leave them for 2-3 minutes. Remove from heat and place onto cutting board. Allow meat to rest for a few minutes before slicing.
  5. Prepare aioli by combining mayonnaise, mustard, and chili powder. If making ahead of time, place into an air-tight container and store in the fridge for up to 2 days after preparation.
  6. To assemble:  Place Swiss on a lower bun, add 6-8 slices of meat, 1/4 cup/60 mL of caramelized onion, and spread a generous amount of aioli on the remaining inside half of the bun before topping the sandwich.
