These are my favorite!

2 Large portabella mushrooms
2 sticks of low fat sting cheese
1/4 c. Crushed tomatoes
1/2 tsp. chopped garlic
dash Italian seasoning
2 tbsp. sliced black olives
(other toppings if wanted)

Preheat the oven 400*

Remove the stems (Can chop them up for extra toppings)
Place the caps on a cookie sheet (non-stick spray) and bake for 8 minutes
After it's done baking Set aside

Put on all your toppings
bake for an additional 8-10 minutes (until the cheese is melted)

with basic toppings 1 top is around 98.7 calories
I usually eat these with a side salad and fruit and it's enough for a meal.

ENJOY!
