Slice your eggplant into ¼ inch rounds and sprinkle evenly with the sea salt. Place the eggplant in a colander in the sink to drain any excess liquid. After around 10 minutes, rinse and pat dry with a paper towel.
Preheat the oven to high broil, and position a rack at the top of your oven.
Line 2 baking sheets with aluminum foil. Arrange the eggplant on the baking sheet and drizzle with the oil.
Broil for around 5-10 minutes, turning the eggplant rounds once. Remove from the oven when the eggplant is softened and golden brown.
Allow to cool for around 5 minutes.
Peel the skin off and transfer to a food processor. Add in the lemon juice, garlic and tahini. Pulse until smooth. Pour into a bowl and top with a drizzle of olive oil.
