Place chicken breast(s) in a saucepan and cover with water. Add rosemary, salt, pepper, bay leaf, garlic, onion and lemon juice.
Cover the saucepan with a lid and put it on the stovetop over medium heat. Bring to a simmer and lower heat to medium-low. Simmer until the chicken reaches an internal temperature of 160℉, about 6-10 minutes, depending on the size of the breast(s).
Remove chicken from water and allow it to cool.* Cut it into thin slices.
Lay out a wrap on a flat surface. Line ¼ of chicken slices across the wrap, slightly off circle to allow room for rolling. Top with ¼ cup guacamole, several tomato slices and ¼ cup baby spinach leaves.
Roll the wrap to form the sandwich (see hack below) and serve immediately. Store any leftovers in the fridge and assemble wraps as needed.
*At this point, the chicken can be stored in the refrigerator for up to 5 days or frozen for up to 4 months.
To make Bechamel sauce, melt butter in a small saucepan. Add the flour, stir until the mixture bubbles. Whisk milk, salt and pepper into the flour mixture and simmer, whisking constantly, until the sauce is thickened.
Remove from heat and stir in 2 tbsp Gruyere cheese, 1 tbsp Parmesan cheese and nutmeg. Stir until cheeses melt.
To assemble sandwiches, spread ½ of the Bechamel sauce on two slices of bread. Top each slice with 2 slices of ham and sprinkle half of the remaining Gruyere over ham. Spread Dijon mustard on the remaining two slices of bread and place, mustard side down, on top of ham and cheese.
Put sandwiches on a baking sheet coated with non-stick cooking spray or lined with parchment paper. Cover with remaining Bechamel sauce and Gruyere cheese.
Bake for 5-7 minutes until cheese melts and the sandwich is heated through. Place under broiler for a few moments, if desired, to brown top of the sandwich.
For a Croque Madame: Top with a fried or poached egg.
Hack: Bechamel sauce can be stored in the refrigerator for up to 5 days. Cover surface with plastic wrap to avoid forming a skin.

Hack: Place burgers on a cookie sheet and place them in the freezer until frozen. Put individually into sealable sandwich bags and then into a sealable freezer bag or freezer container. The rolls can also be frozen in the same manner.
Hack: To extend the shelf life of romaine, separate leave and wash. Dry in a salad spinner or with paper towels. Place lettuce leaves in a sealable plastic bag or container with paper towels between each layer to absorb moisture. Replace paper towels if they become soggy.
