1 1/2 pounds bacon
4 ripe avocados (1 1/2 pounds), pitted and peeled
Juice of 1/2 lime
1 to 2 heads Bibb lettuce, leaves separated, or
1/2 head Boston lettuce
3/4 cup homemade mayonnaise, or prepared
Cook bacon until browned and crisp. Transfer bacon to a paper-towel-lined pan to drain; discard fat.
Place avocadoes in a bowl with lime juice, and mash with a fork until chunky but spreadable.
Using a large serrated knife, split focaccia horizontally. Spread bottom with avocado mixture; layer with bacon, oven-dried tomatoes, and lettuce. Spread remaining focaccia with mayonnaise, and top sandwich.
Cut into 12 squares and serve.
NOTE: This is wonderful made with roasted garlic mayonnaise.
