Instructions

1. 1
   In a medium bowl, whisk together vinegar, water, sugar and salt until dissolved. Stir in carrots, radishes and jalapenos. Cover and refrigerate for at least 1 hour.
2. 2
   In a small bowl, mix together mayonnaise, garlic, sriracha, lime juice, salt and pepper. Set aside.
3. 3
   Place ground beef and mushrooms in a large bowl. Add in garlic powder, onion powder, salt and pepper and mix until just incorporated.
4. 4
   Divide the beef into 8 equal portions. Form each portion into a ½-inch thick burger, making a shallow indentation in the center with your thumb.
5. 5
   Heat grill to medium-high heat. Grill the burgers for 3 minutes on each side, or until slightly charred and cooked to preferred doneness. Remove burgers to a pan and tent with foil; allow to rest for 1-2 minutes.
6. 6
   Place buns on grill, cut-side down, and lightly toast until golden. Spread about 1 Tbsp. of the spicy mayonnaise onto each of the bottom buns. Top with burger patty, cucumber slices, pickled vegetables, mint and cilantro. Enjoy!
