How to Make It
Preheat the oven to 425°. On a rimmed baking sheet, brush the tomatoes with olive oil and season with salt and pepper. Roast the tomatoes for 20 to 25 minutes, until lightly browned in spots and softened. Let cool, then squeeze out and discard the seeds. Transfer the tomatoes to a blender. Add the sherry vinegar, lemon juice, mustard, shallot, egg yolk and garlic and puree until nearly smooth. With the blender on, gradually add the 3/4 cup of olive oil until incorporated. Season the dressing with salt and pepper.
Arrange the lettuce wedges on a platter. Scatter the carrot ribbons and sliced radishes over the lettuce and drizzle some of the dressing on top. Garnish with pumpkin seeds and dill sprigs and season the salad with salt and pepper. Serve right away, passing additional dressing at the table.
