3 tablespoons hoisin sauce
3 tablespoons reduced-sodium soy sauce
2 tablespoons rice vinegar
1 teaspoon sesame oil
2 teaspoons canola or grapeseed oi
1 (12- to 14-ounce) package extra-firm tofu (do not use silken)
8 ounces baby bella (cremini) mushrooms, finely chopped
1 (8-ounce) can water chestnuts, drained and finely chopped
2 cloves garlic, minced note I used 2 tsp ginger/garlic paste
2 teaspoons freshly grated ginger
1/4 teaspoon red pepper flakes
4 green onions, thinly sliced, divided
8 large inner leaves romaine lettuce (from a romaine heart) or butter lettuce leaves
Optional for serving: grated carrots, additional red pepper flakes
Press the tofu between paper towels to squeeze out as much liquid as possible. Refresh the paper towels and press again. Heat the 2 teaspoons canola oil in a large nonstick skillet over medium-high. Once the oil is hot, crumble in the tofu, breaking it into very small pieces as it cooks. Continue cooking for 5 minutes, then add the diced mushrooms. Continue cooking until any remaining tofu liquid cooks off and the tofu starts to turn golden, about 3 minutes more. Stir in the water chestnuts, garlic, ginger, red pepper flakes, and half of the green onions and cook until fragrant, about 30 seconds more.
Pour the sauce over the top of the tofu mixture and stir to coat. Cook just until you hear bubbling and the sauce is warmed through, 30 to 60 seconds.
Spoon the tofu mixture into individual lettuce leaves. Top with remaining green onions, grated carrots, and additional red pepper flakes as desired. Enjoy immediately.
The tofu filling can be refrigerated for 3 to 5 days. Reheat gently in the microwave with a bit of water or stock to prevent it from drying out or in a skillet over medium heat. Try the leftovers mixed with rice or scrambled with eggs!
