To make classic avocado toast, start with one piece of thick, grainy bread toasted until golden brown. Mash half a large ripe avocado with 1-2 teaspoons of freshly squeezed lemon juice, then spread it over the toast. Season with kosher salt and freshly cracked black pepper to taste, and serve immediately. Here is a simple step-by-step guide:

• Toast the bread for 2-3 minutes until golden.
• Remove the avocado pit, scoop out the flesh, and mash it with lemon juice, salt, and pepper.
• Spread the mashed avocado evenly on the toast.
• Optionally add toppings like cherry tomatoes, smoked salmon, scrambled eggs, goat cheese, or pico de gallo for variety.

Variations can include adding garlic rub on warm toast, drizzling olive oil, or topping with red pepper flakes. This basic recipe can be customized to suit personal taste or to create more elaborate avocado toast combinations.
