Add the vinegar, water, and honey to a saucepan and heat on low until the honey dissolves. Remove from the heat and let cool while you prep the avocados.
Slice each avocado in half, then cut each half into 4 slices (about 8 slices per avocado).
Add the garlic and red pepper flakes (if using) to a glass jar along with the avocado slices. Carefully pour the vinegar mixture over the top.
Cover with the lid and refrigerate 2–3 hours before eating.
Great as a snack, on eggs, in a burger or wrap, on tacos, or mashed into a pickled guacamole. From lilsipper on Instagram.
