Start by toasting your whole grain bread until it's golden brown and crispy, about 3-4 minutes depending on your toaster. You want it firm enough that it won't get mushy when you pile on the toppings. Don't panic if it looks darker than regular toast—that crunch is exactly what we're going for here.
While the bread toasts, slice your ripe avocados in half lengthwise and remove the pit by tapping your knife against it and twisting gently. Scoop the flesh into a small bowl and mash it roughly with a fork, leaving some small chunks for texture (don't make it baby food smooth).
Season your mashed avocado with sea salt, freshly ground black pepper, and that tablespoon of extra virgin olive oil. Squeeze the lemon juice over everything and stir gently—this step keeps your avocado bright green instead of brown and sad.
Get a small skillet heating over medium-high heat and add your smoked turkey strips for about 2 minutes per side until they're slightly crispy at the edges. The sizzle sound means you're doing it right, and my kitchen always smells amazing at this point.
Fill a shallow saucepan with water and bring it to a gentle simmer, then crack your egg into the water and poach it for 3-4 minutes until the white sets but the yolk stays runny. If you've never poached an egg before, don't stress—just keep the heat medium and watch it bubble gently.
Spread your avocado mixture generously across each slice of toasted bread, then layer the crispy turkey strips on top. Arrange your halved cherry tomatoes around the turkey and scatter those radish slices for a peppery bite.
Top each slice with a poached egg right in the center, then sprinkle crumbled feta cheese and toasted sesame seeds all over. Serve immediately while the toast is still warm and the egg yolk is runny enough to be your natural sauce.
