In a medium-sized bowl, combine the olive oil, red wine vinegar, balsamic vinegar, Dijon mustard, and honey. Season with salt and pepper. Whisk until fully combined and the dressing has emulsified.
Add the chopped onion, garlic, basil, tarragon, thyme, and chilli flakes. Season with pink salt and black pepper. Mix the ingredients together and allow to rest for 5 to 10 minutes.
Add the cherry tomatoes and toss, ensuring that the tomatoes are well-coated with the sauce.
On a serving platter, place the burrata and top with the cherry tomato mixture. Garnish with fresh basil leaves. Add drizzle of olive oil.
