Cut 2 slices of sturdy bread. Toast the bread in a toaster or in a skillet on the stovetop until golden brown.
Rub the peeled garlic clove over the top of the warm toasted bread, making sure to fully cover the entire surface area.
Next, halve the avocado and remove the pit. Scoop out the avocado flesh from both halves and place it in a bowl. Add a small squeeze of fresh lemon juice (about 1 tsp), salt and pepper to the bowl and mash the avocado with a fork. I recommend leaving it just a little chunky.
Divide the avocado mixture and spread it on top of each slice of toast. Top with a pinch of red pepper flakes and a pinch of sea salt (optional).
*I purchased a loaf of bakery sourdough bread so I could get those nice, thick slices. But you can also use pre-sliced sourdough bread from the bread aisle if you want to save a little extra money.
