I have had variations of this yummy snack at different events and my mouth watered when I saw that our sister-in-law, Maureen, brought this as an appetizer on Thanksgiving. Here's how she made hers.
Fresh basil leaves
Red and yellow grape tomatoes
Salt and pepper
Freshly squeezed lemon juice
Place a ball of mozzarella on a toothpick, followed by a folded basil leaf and topped off with a tomato. Place down in a large pan, drizzle with olive oil, lemon juice and lemon zest and sprinkle salt and pepper on the mozzarella.
I've never had it with the lemon juice and found that I really love that addition.
