How to Make It
Light a grill. In a small bowl, combine the orange juice, soy sauce, chili-garlic sauce and sesame oil.
Insert a toothpick through each onion slice to the center to hold it together. Arrange the onion slices, Portobello caps and chayote slices on 2 large baking sheets. Thread the shrimp onto six 12-inch metal skewers. Brush the vegetables and shrimp with the olive oil and season with salt and pepper.
Grill the onion and chayote over a medium-hot fire until lightly charred, 2 minutes per side. Grill the Portobellos until tender and lightly charred, 4 minutes per side. Return the vegetables to the baking sheets. Grill the shrimp until just cooked through, 1 minute per side.
Thickly slice the Portobellos. Remove the toothpicks from the onion slices and separate into rings. Drizzle 3 tablespoons of the dressing over the vegetables and toss them together. Mound the vegetable salad on plates and top with the shrimp skewers. Drizzle with the remaining dressing and serve.
