5. Dinner Party. Chances are you've got friends who are also wondering what to do on V-Day. Invite them all over for a dinner party. You could even do it Iron Chef-style, and ask everyone to bring a dish that incorporates one ingredient.
6. Dessert. To keep it ultra low-key, do everything as you normally would, but eat a luxurious dessert—cheesecake, red velvet cake, chocolate torte. Go to a bakery the day before and pick out two servings of your favorite sweet dish. It's a fast and easy way to indulge and celebrate.
