How to make a vegan Oyster Mushroom Po' boy sandwich at the

We always enjoy our time along the Georgia coast, and in Savannah we have a few vegan restaurants on heavy rotation. Be sure to check out Fox & Fig plant-based cafe the next time your in Savannah. But Savannah is known for seafood. So after our last trip to Savannah we needed to figure out a good vegan shrimp substitute.


In our gluten-free vegan shrimp Orzo we used a wonderful product called King Prawn. The only issue is it can be tricky to find sometime. If you see it make sure to grab a couple of packs, it makes a great freezer staple for anytime you get a seafood craving.

We had a great vegan scallops dish for dinner earlier in the year. They used the stems of oyster mushrooms for the scallops. The texture and favor were so good we decided to give them a try for our vegan version of Oyster Mushroom Po Boy.

Before this recipe portobello and shiitake mushrooms had been our go to of choice. The mushroom’s texture make them a great vegan meat substitute. In the store Oyster mushrooms look a little alien and intimidating but after this recipe, there our new favorite.

Oyster mushrooms are soft with a slightly chewy texture. When cooked, they have a mild and nutty, seafood-like flavor. Oyster mushrooms are best used in stir-fry, sautéed or as a seafood sub like in this po’boy and for calamari too.

Nutritionally speaking Oyster mushrooms per 1 cup serving contains 2 grams of fiber and 3 grams of protein. They’re also a source of vitamin B6 and D.
