In a large saute pan, heat extra virgin olive oil over medium-high heat. Add chicken or tofu and mushrooms and cook for 10 minutes, until browned. Stir in ginger, garlic, scallions, soy sauce, red pepper flakes and silan. Cook mixture for 4 minutes more, then taste and adjust seasoning with salt and pepper. Remove from heat.

To serve, layer two lettuce leaves per wrap. Scoop a heaping spoonful of brown rice into each lettuce cup, then a spoonful of the mixture, then sprinkle with peanuts, and serve immediately.
