Happy Valentine's Day to You!
Start with a beautiful sparkler that needn't cost much. I heartily recommend a New Mexico sparkling wine such as Gruet rather than splurging on French champagne. Despite all, I've found sparklers do keep a day two. Or, if you'd like, choose a half-bottle of a very special sparkling wine from the wine shop. Add some of the tapenade with baguette or crackers or a bowl of great potato chips--my favorite sparkler pairing. Stay away from cheese; fresh vegetables would work wonderfully. Just stick with something light; lamb is loving, but filling.
If you're cooking for just you, open the wine, turn on the music, set the table, and enjoy a beautiful night. Afterward, get out that novel you've been meaning to read and take it to bed with you along with the last glass of wine or put on a great movie you've been saving. You could write letters or cards to a few people you adore; make yourself post them in the morning. Whatever you do, have fun cooking and taking care of yourself!
