It's one of those things I couldn't even imagine doing before having my kitchen redone/renovated. I had spent the previous year without a functioning oven. Now, thank Gd, I have two turbo ovens, one for meat and the other parve, in which I can bake more than one thing at a time. Having two ovens makes a kosher kitchen very easy to cook in. We hardly eat anything dairy, so the second oven has remained parve, meaning neither meat nor dairy. I make lots of side dishes, fish, cakes and challot in it.
While vegetables for Shabbat were baking in the oven I took a smaller oven pan, covered it with baking paper, and then cut onion, squash, pumpkin, cabbage, tomato and two eggs. I topped it with a bit of vegetable oil, and then into the oven it went. Once I could see that the eggs looked cooked, I checked the vegetables with a fork, to see if they were soft. I don't pretime my cooking, since there are too many variables.
My lunch, Baked Vegetable Omelet, was delicious, and the pan didn't even get dirty.
