Use portobello mushroom caps that are 3 1/2 to 4 inches across, they will shrink when grilled. Use smaller caps for appetizers. These are not very 'spicey', and we used canned corn. No big deal. It does need to be spiced up.
We got it from a Pillsbury Vegetarian cookbook.
This is a delicious recipe we found in a "Taste of Home" magazine. We recommend you use smaller shrimp, or slice the bigger ones in half to make them more manageable for eating. If you left out the shrimp, it would make an excellent hot party dip or spread.
These are Great!! We found them in the "Taste of Home crazy for cupcakes". The recipe is for jumbo cakes, but we don't have a jumbo pan. I ended with almost 2 dozen cakes. Everyone liked the smaller ones, some thought jumbo cakes would have been to much.
