In a small omelet pan (6 or 8 inches), saute veggies with drizzle of oil, or broth, and salt and pepper if using. I add the greens last. Add the protein here if it needs to be cooked. Set aside. A trick I use is to add the cheese here. Dairy free cheese tends to take longer to melt so if you warm it with the cooked veggies it will melt better.
Using the same pan, pour the vegan egg in (put oil in first if using) and cook over medium low heat.
Allow it to firm up a bit then flip carefully. See note for a trick I use.
Once you see them firm up, add the cooked veggies, cheese and protein to one half of the egg.
Cook until you see the cheese melting and you look under the egg and see it brown.
Slide onto a plate and fold the empty side over to serve!
Notes
Use any veggies you love, just be mindful of the ones that will give a watery result, and saute those well.
A tip to flip the egg over if you are having trouble, you can slide it onto a plate and then slide it back into the pan on the other side.
This makes one omelet enough for two people as it is pretty stuffed!
