1 lb boneless chicken breasts
1-2 teaspoons Montreal Chicken seasoning
4 rolls
1 cup cheddar-jack cheese, shredded
2 avocados
1 small tomato, diced
1 package guacamole mix

Heat a stove top non-stick grill pan to medium-high. Season the chicken breasts with the Montreal Chicken seasoning. Grill the chicken for 2-3 minutes on each side or until cooked through. Slice the chicken and set aside.
To prepare the guacamole, split each avocado in half, discard the pit and scoop out the meat into a bowl. Mash the avocado with a fork leaving small chunks. Mix in the tomato and guacamole mix. Stir and set aside.
To assemble the sandwich, place a layer of chicken on the bottom of the roll. Sprinkle a good amount of cheese on top of the chicken and place in a pre-heated broiler to melt the cheese. Put a nice scoop of the guacamole on top and then place the top of the roll on top.

Enjoy! And of course, if you have the time, fresh guacamole from scratch would be even better!
