Cherry Tomatoes filled with Pesto
These are super easy and most of the preparation can be done hours ahead. If the tomatoes are ripe and you have a good brand of pesto you guests will love them. They are a particular treat during the summer months when you can get really fresh and ripe tomatoes.
I usually have a small jar of homemade pesto in the freezer which is fantastic, because of course, they are better with homemade pesto. But there are one or two brands that work perfectly well for this.
