Method

  1. 1

    Cook the Bacon

    Lay the **8 slices** streaky bacon of bacon in a single layer in a large, cold skillet. Place over medium heat and cook, turning occasionally, until golden brown and crispy. This usually takes about 8-10 minutes.

    Once cooked, transfer the bacon to a plate lined with paper towels to drain excess grease. Set aside.

    For perfectly flat and evenly cooked bacon, try baking it! Arrange the slices on a wire rack set over a baking sheet and bake at 200°C (400°F) for 15-20 minutes, no flipping required.

  2. 2

    Prepare the Toppings

    While the bacon is cooking, prepare your other ingredients.

    1. Wash and thoroughly dry the **4 leaves** romaine lettuce of lettuce.
    2. Slice the **1 unit** large tomato tomato into even rounds.
    3. Halve the **1 unit** large ripe avocado avocado, remove the pit, and either slice it or gently mash the flesh in a small bowl.

    To prevent the avocado from browning if you're not assembling immediately, spritz it with a tiny bit of lemon or lime juice.

  3. 3

    Toast the Bread

    Toast the **4 slices** sourdough bread of bread until they are golden brown and crisp. You can use a toaster, or for extra flavor, toast them in the skillet with a little of the reserved bacon grease over medium heat.

    Toasting the bread is crucial! It prevents the sandwich from becoming soggy from the tomato and mayonnaise.

    Assemble the Sandwiches

    It's time to build your 2 sandwiches!

    1. Spread a generous layer of **60 ml** mayonnaise of mayonnaise on one side of each slice of toasted bread.
    2. On two of the slices, layer the ingredients: start with the lettuce leaves, followed by the tomato slices, the crispy bacon (you can break the slices in half to fit), and finally the sliced or mashed avocado.
    3. Lightly season the layers with **1 g** salt of salt and **1 g** black pepper of pepper.
    4. Top with the remaining two slices of bread, mayonnaise-side down.
