Cook the bacon slices according to package instructions and allow to dry on paper towels.

In a small dish, combine the mayo, basil and lemon juice and stir until well combined and set aside.

Toast the bread slices in a toaster until golden. Take two toasted slices and lay them side by side. Spread 1 tablespoon of the basil mayo onto one of the slices. Place 2 oz of the deli turkey or chicken over the mayo and spread avocado slices from ¼ of an avocado over the meat. On the other slice of bread, stack 1-2 pieces of lettuce and one slice of tomato. Criss cross two slices of the cooked bacon over the tomato. Flip the BLT side over onto the turkey side to form a sandwich. Repeat with the three remaining sandwiches. Cut in half and serve (you may want to stick a sandwich pick into each half before slicing to keep the ingredients perfectly stacked).
