Toast the sliced almonds in the oven preheated to 180ºC until they begin to brown. Peel the carrots and grate with a grater with large holes. Wash the leek, chop it finely and let it dry in a pan with a little oil, then cool it quickly in the blast chiller for ten minutes.
Chop the sandwich bread in a mixer with the eggs, the leek cooled, a pinch of salt, a grated pepper, some basil leaves and lemon juice. Mix the mixture with the grated carrots and 60 g of roasted almonds. Cover with baking paper a loaf mold, distribute the remaining roasted almonds on the bottom, fill with the mixture and cook in the preheated oven to 180°C for 40 minutes.
