Make the guacamole by scooping out the avocado flesh, adding a squeeze of lemon juice, and mashing it with a fork. Finely chop the onion and add it in. Add a pinch of salt, a few drops of Tabasco if you like it spicy, and a drizzle of extra virgin olive oil. Mix everything together. For this recipe, don't add tomato to the guacamole, since you'll serve it on top of the toast. This keeps the guacamole extra smooth.

Toast the bread. Peel and chop the tomato. Lightly toast the pine nuts in a pan with a few drops of oil.
