i had one of the simplest breakfasts ever the other day at a small cafe, and now i'm hooked - Avocado toast. Mashed avocado with a bit of salt and pepper, spread on a good quality toasted bread (french loaf works well), drizzled with a bit of lemon or lime juice, balsamic vinegar, and crushed red pepper flakes. If you want to get real fancy, put some garlic oil on the bread before topping it with avocado.
