Season the shrimp lightly with salt and toss with 1 teaspoon curry powder. Heat 2 tablespoons vegetable oil in a large nonstick skillet over high heat. Add the shrimp and cook until lightly browned around the edges and just cooked through, 1 to 2 minutes per side. Remove to a plate.
Add the remaining 3 tablespoons vegetable oil to the skillet along with the onion and scallion whites. Cook, stirring occasionally, until softened and lightly browned, about 3 minutes. Stir in the almonds, ginger, garlic and remaining 1 teaspoon curry powder. Cook, stirring, until the almonds are lightly toasted, about 1 minute. Add the white rice, riced cauliflower and 1/2 teaspoon salt. Cook, tossing and breaking up any clumps, until lightly toasted and heated through, about 3 minutes. Add the shrimp and toss until warmed through, about 1 minute; season with salt.
Divide the fried rice and shrimp among bowls. Serve with sliced cucumber, mango chutney, plain yogurt and lime wedges. Top with the scallion greens.
Try mixing white rice with riced vegetables, like we did for this dish. It’s an easy way to get extra nutrients!
