Preheat a grill pan or skillet over medium-high heat (or preheat a toaster). Brush both sides of the sourdough slices lightly with 1 tablespoon olive oil.

Toast the bread until golden and crisp, about 2–3 minutes per side in the skillet or 3–4 minutes in a toaster, adjusting to your preferred crispness. Sprinkle the warm toasts with a pinch of the 1 teaspoon salt while still hot.

Avocado spread

Halve the avocado, remove the pit, and scoop the flesh into a bowl.

Add 1 teaspoon lemon juice, 1 teaspoon extra-virgin olive oil, 1 teaspoon fine sea salt, 1 teaspoon freshly ground black pepper, and 1 teaspoon red pepper flakes to the bowl.

Mash with a fork to your desired texture — smooth for easy spreading or slightly chunky for more texture. Taste and adjust seasoning with more lemon, salt, or pepper if needed.

Assemble & serve

Divide the avocado mixture evenly and spread it onto the two warm toasted slices.

Top each slice with optional toppings as desired: scatter halved cherry tomatoes, a sprinkle of microgreens or arugula, crumbled feta, and a pinch of everything bagel seasoning.

Finish with a small drizzle of olive oil or an extra squeeze of lemon if desired. Serve immediately.
