Preheat your oven t 350”F. Slice the cherry tomatoes into 3 slices lengthwise. Layer them in a single layer on a large oiled baking sheet.
Drizzle with a lug of olive oil over the top and sprinkle with a good pinch of sea salt to your taste. Roast for 35 minutes in the preheated oven or until nicely caramelized around the edges.
Meanwhile cut the scallions (both greens and whites) into chunks. Add them to the bowl of a food processor with the olive oil and lemon juice. Puree until smooth. Transfer to a bowl and season to taste with sea salt. Adjust the dressing to your taste with more lemon juice, sea salt and olive oil to your desired consistency.
Tear the burrata cheese into chunks and place it on a serving platter. Top with the roasted tomatoes and generously drizzle over the top with the scallion dressing. Garnish with chives and chive blossoms.
