Sometimes, you just need a really simple salad. Last week was just such a time. I was overwhelmed at work, busy and home, and generally a bit wiped out. Cooking anything with a measure of complexity was simply beyond my means, and so I turned to one of the simplest standbys I know.
Sliced tomatoes (heirloom or otherwise; just make sure they're tasty and not bland), sliced red onion, torn basil, good balsamic vinegar (it should be a bit syrupy and rich and a bit sweet, not runny and tangy) and sea salt.
It satisfies the tummy and the soul.
