Preheat the oven to 400 degrees F (204 degrees C).
Arrange the zucchini in a single layer on a large baking sheet. Brush with olive oil, then sprinkle both sides lightly with sea salt.
Roast the zucchini slices in the oven for about 20 minutes, until tender.
When done, remove the zucchini from the oven but leave it on at 400. Pat the zucchini with paper towels to soak up any extra water or oil.
Meanwhile, heat the remaining 1/2 tablespoon (7.39 ml) of oil in a saute pan or cast iron braiser on the stove over medium-high heat. Add the ground beef, and season with salt and pepper. Cook for about 10 minutes, until browned.
Add the diced onion. Cook for 7-8 minutes, until onions are translucent and starting to brown.
Arrange the zucchini slices at the bottom of a 9x13 casserole dish, overlapping slightly. Pour 3/4 cup dressing over the zucchini and spread evenly. Top with the meat, then sprinkle with shredded cheese.
Bake for 10-15 minutes, until the cheese on top is melted.
Top the casserole with lettuce, tomatoes, and pickles. Drizzle with the remaining 1/4 cup dressing. Sprinkle with sesame seeds.
Serving size: 1/8 entire casserole
