These quick Vegetarian Lettuce Wraps are loaded with coconut rice, roasted veggies in soy and sriracha, and finished with a zesty green onion vinaigrette.
Preheat oven to 425℉. Combine rice, coconut milk, and 1/4 teaspoon salt in a small pot. Stir. Bring to a boil over high heat, then reduce to low, cover, and simmer about 15–20 minutes or until coconut milk is absorbed. Remove pot from heat (keeping it covered) and let stand undisturbed 10 minutes, then fluff it with a fork and stir in 1 finely sliced green onion. Set aside and keep warm.
While rice cooks, peel sweet potato and cut into 1/2-inch rounds. Cut rounds in 1/2-inch pieces. Quarter the mushrooms.
Whisk together soy sauce, sriracha sauce, 3 teaspoons brown sugar, and 1 tablespoon canola oil in a small bowl. Line a sheet pan with parchment paper (the mixture gets sticky!). Place chopped sweet potatoes and mushrooms on the sheet pan and pour the mixture over. Stir to mix, and space out the veggies in a single layer. Bake 10 minutes, flip veggies with a spatula, then bake another 10–15 minutes or until veggies are tender. Remove from oven and season to taste with salt.
While veggies are roasting, add rice wine vinegar, remaining 3 tablespoons canola oil, remaining teaspoon brown sugar, minced ginger, and remaining thinly sliced green onion. Season to taste with salt. If desired, add crushed red pepper flakes. Stir dressing until combined.
Wash and thoroughly (but gently) dry lettuce. Double up 2 pieces of lettuce or use single pieces of lettuce, depending on how thick your lettuce is. Fill lettuce cups with a generous spoonful of rice. Add veggies on top and drizzle dressing on generously. If desired, garnish with crushed cashews and a thinly sliced cucumber. Season with additional salt and pepper if needed. If desired, add a tiny drizzle of sesame oil or lime juice. Serve extra rice on the side with any leftover dressing. Serve immediately.
Notes
Storage: Store leftover lettuce, coconut rice, roasted veggies, and vinaigrette separately in airtight containers. Keep in the fridge for up to 3 days. Assemble wraps fresh when ready to eat.
