Mignon and Blue Cheese Slider

In a small bowl, combine 4 tablespoons vinegar and sugar, stirring until sugar dissolves. Add shallots to vinegar mixture; toss. Cover and chill 30 minutes. Toss. Drain and set aside.

Preheat grill to direct heat over medium-high heat.

In a large bowl, combine remaining 1 tablespoon vinegar, oil, mustard and soy sauce, stirring with a whisk. Add arugula and chives; toss gently to coat.

In a small bowl, combine mayonnaise and cheese; set aside.

Grill patties about 8 to 10 minutes, flipping once, or until temperature reaches 160 degrees.

Spread the bottom half of each bun with mayonnaise mixture. Top with slider, arugula mixture, pickled shallot and bun top.
