These were great. You can honestly stuff mushrooms with whatever you've got lying around.
These were Cremini, cleaned and stuffed with the following:
1 clove garlic
2 Sundried tomatoes (I buy the marinated ones, someday I will make my own)
1 Roma tomato
1/4 Cup Sunflower seeds
1/2 Cup of salad dressing (some left over creamy something that was in the fridge).
Salt and Pepper to taste.
Toss everything in the blender until you get the consistency you desire, stuff the mushrooms and eat!

They were yummy. You can't mess up something like this, I served them with a side salad and had plenty to eat!
