Avoid overly heavy foods and keep it classy. Good choices for the main course include small sandwiches, fresh salad, avocado, or a baguette with specialty meats. Mediterranean foods are also great for romantic picnics.   Avoid messy things like pizza or chicken wings. Think of foods that are simple to eat and won’t leave a residue on your hands, or stains on your shirt.  Ask your date if they are a vegan or vegetarian and make sure to see if they have any food allergies. Bring things you can snack on while you talk to your date. Think of snacks that don’t require the use of any utensils like nuts, chocolate, a cheese plate, or olives. Instead of cheap snacks like potato chips, use apple chips as an alternative.  Fruit like strawberries, blueberries, or cut up melon is a great snack. Hummus and pita bread are a romantic snack both of you can share. Just avoid the garlic variation. If you’re going to bring candy, try to keep it mature. Things like sugar-coated nuts or high-quality chocolate are better than the cheap stuff you’d find at a gas station. You can pack champagne, non-alcoholic champagne, or even seltzer water in flutes for a picnic. If you’re younger or need to drive, you should pick the non-alcoholic alternatives.   Champagne has long been known as one of the most romantic alcoholic beverages in our culture.  If you’re on a tight budget, you can get sparkling wine as an alternative. Remember to bring a corkscrew so you can open the bottle! You can keep your drinks chilled with a cooler filled with ice. If you don't bake you can pick up fresh cookies or specialty sweets like cannolis or chocolate croissants at a local bakery. However, if you’re on a limited budget or like to bake, making desserts at home is a cheaper alternative.   Chocolate has properties which promote good feelings and have positive health results.  If you don’t feel confident with your baking skills, go with the instant bake items that are found in boxes.
