It sounds weird but grapes with feta or goat cheese.Do you add other ingredients to the omelet? Fresh or cooked?
Thinking more along the lines of a "sunday sauce". Something with ground meat and sausage. Probably mushroom zucchini and the like.
I make spaghetti sauce a lot. Fresh mushrooms (never canned) and red peppers are a must for me. Carrots and a little red wine if it's a Bolognese sauce.
