Will's Portabella Burger

I created this one while my wife was on vacation.

Seasoning

Sugar
chili powder
cayenne pepper
Black pepper
lemon pepper

Take one large portabella mushroom and snap off the stem.
Spray the mushroom with olive oil (I use a finger pump sprayer)
Place it on the hot grill (around 350-400 degrees or so)
Grill for a few minutes with just the oil
Before the first flip, respray with oil, and sprinkle seasoning
Once flipped, repeat.
