What are some recipe substitutions for the vegan pepper steak?

There are several substitutions that can be made with this recipe. First off, you can use another type of mushroom such as king oyster or lion's mane. Both have a hearty texture and will do a good job of soaking up the sauce. You can also follow this recipe to make tofu steaks. It's best to use super firm tofu and cut it into thick strips.

Other vegetables that can be added in with the peppers or can replace them are zucchini or eggplant. Leave the skin on both and cut them into thick bite-size pieces. Broccoli and cauliflower are also 2 vegetables that would be delicious. Just trim them to bite-size florets. Carrot ribbons, snow peas, and snap peas are also good options.

If you don't have tamari, feel free to use soy sauce or coconut aminos. To thicken the sauces arrowroot powder, tapioca starch, or potato starch will get the job done just as well as cornstarch. Instead of maple syrup, you can swap coconut sugar, agave nectar, or date syrup. The white miso paste is an important ingredient, but an extra tablespoon of tamari or soy sauce will do the trick if necessary. In terms of the rice, any other grain can stand in like quinoa, farro, sorghum, or couscous.

What are other ways to serve vegan pepper steak?

The vegan pepper steak is a versatile meal that can be multi-purposed in many ways. For a fresh and crunchy option, scoop the pepper steak into lettuce cups. Butter lettuce, endive, or romaine leaves work well. This could act as an appetizer or the main meal. Turn the pepper steak into a noodle dish by tossing it with cooked soba, udon, or rice noodles. You can make it more brothy by adding a cup more vegetable broth to the skillet.

Make an Asian Buddha bowl by serving the mushrooms over noodles along with extra vegetables like shredded carrots, steamed shelled edamame, sauteed baby bok choy, steamed broccoli, or shredded purple cabbage. If you want to change up the sauce, mix together peanut butter, soy sauce, lime juice, sriracha, and maple syrup to infuse new flavors.

For a heartier comfort food option, try the vegan pepper steak stuffed into a baked russet or sweet potato, and add extra sauce for topping. Or stuff the filling into hearty ciabatta bread to make a delicious sandwich.
