What can you use as a substitute for goat cheese?

You could try a whipped feta.

Trader Joe's currently has an Israeli feta in a yellow and green package and I sometimes see it at WF and my local organic market.

For an omelet with vegetables you can use almost any cheese you like. The goat cheese is just making it special, but I wouldn't rule out any melting cheese either, or just some parmesan or other hard cheese sprinkled on the veggies.

Good to know, healthier kitchen. I never knew that...

If you can find it, try Israeli feta as it milder and slightly less salty than some of the others.

Same here. Feta would work great.

Yes, like Kristen W., if I don't have goat cheese on hand for a Mediterreanan dish, I use feta. Different but equally delicious!

Well, feta has a different flavor than goat but will generally work with Mediterrenean ingredients.

The dish is a Mediterranean veggie omlet

It will depend on the dish... Could you provide more info? In terms of flavor, there is no real substitute, but you could use an entirely different ingredient and give the dish a new spin...
