best simple avocado toast
toast and sprinkle kosher salt on good bread (or if you wanna be me, Ezekiel's Sprouted Grain English Muffins) and then mash 1/3 (or more) of a ripe avocado on top with a fork. top with lemon, a little more sea salt, and pepper. red chili flakes are also pretty standard.
to make less simple: radish slices, watercress, sunflower seeds... go nuts ;)
