Make the sunflower romesco: In the bowl of a food processor, combine the sunflower seeds, roasted red peppers, garlic, paprika, aleppo pepper, vinegar, tomato paste, parsley, salt, and pepper. Pulse the mixture until all ingredients are finely chopped and lightly pasty. Scrape the bowl down. Then, with the motor on low, drizzle the olive oil in through the feed tube until fully incorporated. Check the sauce for seasoning. Transfer sauce to a sealable jar, and set aside in the fridge until ready to use.
Preheat the oven to 350°F.
Cut the eggplants in half lengthwise, right through the stem. Using a paring knife, carve into the eggplant flesh all the way around the perimeter. Pry the eggplant flesh out of the eggplant halves with your fingers or a spoon and set it aside. Place eggplant halves on a baking sheet, facing up. Brush the eggplant halves with olive oil and season with salt and pepper. Bake eggplant for 20 minutes, or until golden brown and lightly tender.
Roughly chop the scooped out eggplant. Heat a bit of oil in a medium-large sauté pan over medium heat. Add the shallots and garlic to the pan and sauté until fragrant and slightly soft, about 2 minutes. Add the chopped eggplant, and season with salt and pepper. Stir. Sauté the eggplant, stirring occasionally, until tender, browned, and slightly reduced in size, about 4 minutes.
Carefully transfer eggplant to the food processor. Add the ¼ cup of romesco, lemon juice, and tahini to the food processor as well. Pulse the mixture until you have a chunky paste.
To serve, divide the warm eggplant filling evenly among the eggplant “boats.” Then, spoon your cooked grain of choice on top along with a sprinkle of chopped herbs. Garnish the tops of the stuffed eggplants with more romesco and toasted sunflower seeds or dukkah. Enjoy warm.
