Italian Halibut

I don't like fish much, but I love this recipe!

3 halibut fillets
2 medium sized tomatoes, small dice
1/4 cup mushrooms, sliced
1/2 cup spinach, chopped
1/4 cup (or less) fat-free italian dressing
S&P TT

Mix last 5 ingredients together and let marinade for 10 minutes (or over night).

Place halibut on baking tray, and cover with salad mixture.

Bake for 15 minutes, or until done.
