so my moms tomato plants...

No really, it’s good.I know most people just think of distilled white vinegar when vinegar is mentioned, but balsamic is a darker, thicker, sweeter vinegar.
I make mine like this:

Tomatoes, thick sliced or chunks
Fresh mozzarella sliced
Fresh Basil
Maybe a tiny bit of diced red onion
Equal parts balsamic (important, any other vinegar won’t work), and olive oil.
