- 1 lb cherry tomatoes, quartered
- ¼ sweet onion, thinly sliced into half moons
- 2 Tbsp extra virgin olive oil
- 2 Tbsp red wine vinegar
- 1 tsp Kosher salt
- ¼ tsp freshly ground black pepper
- Flaky sea salt
Add to a bowl. Place quartered tomatoes and thinly sliced onion in a large serving bowl, then season with 1 tsp Kosher salt and ¼ tsp black pepper.
Pour the marinade on top. Drizzle 2 Tbsp extra virgin olive oil and 2 Tbsp red wine vinegar right on top.
Toss the salad. Toss to thoroughly coat, then taste and adjust seasoning as needed. Either serve immediately (with a pinch of flaky sea salt, if using) or cover and refrigerate for 1-2 hours, or up to 24 hours. Can be served cold or at room temperature.
- Tomatoes: If using larger varieties (heirloom, beefsteak), cut into chunks and serve immediately—they soften faster than smaller tomatoes in the marinade.
