SusanV's omelette for one

I tried to make this recipe with one big change--I made it a vegan omelette for two. I followed the recipe exactly, which is a rare thing in our household. I put it in the pan, waited and waited for it to cook, but it just wasn't working. When I tried to peek under the edges to see if it was cooking, it ripped. In one spot, it was starting to burn. So Andy poured the other half of the batter into the pan and we turned it into scrambled eggs instead. But, because it was so liquidy and cornstarchy, it was still fairly gooey even when it was fully cooked. Here it is, my disaster of a vegan omelette for two, with mushrooms, red capsicum and tomato.

It's obviously not the recipe, because it worked for Susan and a few other bloggers, but maybe turning it into a vegan omelette for two fundamentally changed it or something. That's all I can think of, anyways...
