Heat your cast iron pan over high heat. Once it’s smoking, lower to medium. Add in some vegan butter or oil. Add in the mushrooms
Cook down the shiitake mushrooms until lightly browned over medium to medium high heat. I like to leave the mushrooms untouched for 2-3 minutes at a time to lightly brown each side.
Once the mushrooms are cooked to your liking, move them to the sides of the pan.
Add a bit more oil or butter on the centre of the pan.
Rice: place the rice in the centre of the pan. I packed my rice in a bowl and then flipped the bowl over to create a dome shape.
Add the vegan mayo/butter over the rice, pepper, corn kernels, and scallions over the rice. Drizzle generous amount of your sauce of choice (sweet brown sauce or teriyaki sauce) over the rice and mushrooms. Mix together until everything is well coated in the sauce and butter/mayo. Finish off with more pepper, if you like.
Enjoy immediately while still hot.
