Add the salt to the meat. Using your hands form into 4 burger patties about 1.5cm (1/2 in thick).
Place patties on a rimmed baking sheet or tray. Drizzle with a little oil and bake for 10-15 minutes or until burgers are browned and no longer pink in the middle.
While the burgers are cooking, fry almonds in a pan on a medium high heat with a little oil until golden brown. Place on paper towel to cool for a few minutes.
Place toasted almonds in a medium bowl with lemon juice, chopped mint, 3 tablespoons extra virgin olive oil and pinch of salt. Stir. Taste and season with more salt and/or lemon juice as needed.
When the burgers are cooked, divide between 2 plates. Top with salsa and serve salad leaves on the side.
