Here's What You'll Need
cherry tomatoes, sweet onion, olive oil, red wine vinegar, salt, pepper, flaky sea salt
Place quartered tomatoes and thinly sliced onion in a large serving bowl, then season with salt and black pepper. Drizzle extra virgin olive oil and red wine vinegar right on top.
Toss to coat, adjust seasoning as needed. 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.
