Tomato and fresh mozzarella salad with balsamic vinaigrette

This was a quick, easy and tasty salad.

Dice a tomato.

Dice a ball of fresh mozzarella cheese (about 1 1/2" in diameter).

Add a few leaves of basil, chopped.

Season with salt and pepper.

For the balsamic vinaigrette:

In a separate container, add some balsamic vinegar, olive oil, salt, pepper and a tiny bit (1/8 tsp.) of Dijon mustard. Stir, and ideally shake. I made it in a tiny Pyrex container with a rubber lid that seals well.
