Prepare your chicken by pounding out the chicken very thin but not too thin (about ¼ inch thick). You can also butterfly your chicken really thin if that is easier.
4 boneless chicken breasts
Sprinkle liberally 2 tablespoons of your Adobo seasoning all over the chicken (from and back) and set aside.
Pre-heat an outdoor grill or a grill pan on medium heat.
Add your green beans to a medium pot filled with water and bring to a boil.
2 ½ cups green beans
Cook the green beans for about 4 minutes, then drain and set aside.
Slice your tomatoes.
4 medium tomatoes
Remove the flesh of the avocados from the shell and add to a bowl.
2 avocados
Add your lime juice and salt to the avocados and give them a good mash until it is all broken up and mostly smooth. Set aside.
1 lime, 1 teaspoon kosher salt
At this point your grill should be nice and hot.
Spray or brush the grates of the grill or grill pan with a little vegetable oil.
Add your chicken and cook for about 5 minutes per side or until cooked all the way through.
When the chicken is done, remove it from the grill on to a plate and cover with aluminum foil.
Assembling the Chacarero
Place a sliced roll on a plate.
4 bulky rolls or 4 pieces of naan
Add 2 slices of your muenster cheese to the roll.
8 slices of muenster cheese
Then add 2 slices of tomato.
Sprinkle a little of your Adobo seasoning on the tomatoes.
Adobo seasoning
Add a chicken breast on top of the tomatoes.
Add a ¼ of your green beans on top of your chicken.
Sprinkle with a little more Adobo.
Take the top of your roll and take a large heaping spoonful of your avocado mash and spread it around evenly.
Place the top of the roll on the sandwich.
Repeat these steps to make the rest of your Chacarero sandwiches.
