Cover a small tray with wax paper or parchment. Fill a large bowl with warm water. Dip 1 round rice paper in water for 8 to 10 seconds, until just softened and pliable. Lay flat on a wooden cutting board. In a row across the center, place one-quarter each of crab, mango, carrots, beet, bell pepper and mint, leaving a 2-inch border. Fold in sides, then roll forward tightly and lay on prepared tray. Repeat with remaining ingredients. Slice each roll in half before serving.
We’ve spiked these beef burgers with grated beet and carrot to add a hint of sweetness and a healthy dose of fiber. Any whole-grain bun or lettuce wrap works well with this burger – then add your favorite toppings such as tomatoes, onion and lettuce.
