Leo (July 23 to August 22)
Go all out at lunchtime—why not? Leos love to live it up, which could mean anything from a midday steak to, well, these decadent open-face sandwiches. They're vegetarian, but don't let that fool you into thinking they're lacking in richness. The recipe calls for slices of whole grain bread you brush with olive oil and toast; then, to contrast their crunch, you top each with pieces of creamy fresh mozzarella and avocado, sprigs of peppery watercress, some fried sage leaves and a drizzle of herby pesto for an extraordinary afternoon meal.
