Cook and cut your meat up (I used left over beef tenderloin but you can use flat steak or whatever kind of meat of your choice).
Take a fork or spoon and remove the black insides of the mushrooms.
Three types of cheese (cut them up).
White mushrooms (cook these prior to putting them on the Portobellos).
Get charcoal for the grill.
Add add some wood chips (soak wood chips for 15 min. before putting on grill).
Start adding cheese to the portobellos.
Add the meat, mushrooms and more cheese.
Grill smoking (get grill temperature up to 300 degrees +/-).
Just taken off the grill.
Finished and ready to eat! (Cut and enjoy - so good)
