One of my favorites is a good party food. Buy cherry tomatoes. Wash them. Cut the tops off and reserve (if you want). Use a melon baller or a small spoon to scoop the guts of the tomato out. Discard. Turn the tomatoes upside down on paper towels for about a half an hour to drain the juice off.
Meanwhile, cook some bacon until crisp. Crumble it and mix with some mayo and sliced green onion. You can add parsley to this. You can also add parmesan cheese. Some recipes call for this but I've never tried it. Add enough mayo to hold it all together. Stuff the tomatoes with this mixture and place them on a platter that has been lined with a bed of curly parsley. This prevents them from rolling around. You can cap them with the tops if you want. If you do, you'll need to spear them with a toothpick (preferably a decorative one) to keep them in place.
These need to be made fresh but you can keep them in the fridge for up to two hours.
