Homegrown cherry or grape tomatoes marinated in aged balsamic vinegar heighten the flavor of this simple grilled fish.

This recipe is similar to my Grilled swordfish with fruit salsa recipe in that it takes about 30 minutes to make.

It’s a milder tasting fish that the whole family loves.

The secret to the balsamic tomatoes is homegrown, straight from the garden variety. If you don’t have that get to your local farm stand or pick up a container of Campari tomatoes at your grocer. They won’t disappoint.

Using aged balsamic vinegar is different than the old standard variety in that has been aged for decades and the result is a rich and sweet vinegar that is ideal for flavoring with fish, chicken and steak.

This vinegar is typically used after the cooking has finished.

It’s absolutely amazing on tomatoes with fresh basil. Spooned over top of grilled mahi-mahi, this dish will be a regular in your barbecue rotation.
