Preheat your oven to 400°F (200°C).
Slice the zucchini into half-moons and toss with 1 teaspoon of olive oil, salt, and pepper.
Spread the zucchini on a baking sheet and roast for 15-20 minutes until tender and caramelized.
Season the flank steak and shrimp with a pinch of salt and pepper.
Heat the remaining 1 teaspoon of olive oil in a skillet over medium-high heat.
Sear the steak for 3-4 minutes per side for medium-rare; remove from the pan and let it rest before slicing thinly against the grain.
In the same skillet, sear the shrimp for 2 minutes per side until pink and opaque.
In a small bowl, whisk together the tahini, maple syrup, and a squeeze of fresh lemon juice, adding a teaspoon of water at a time until it reaches a drizzling consistency.
Place the spring mix in a large bowl and top with the roasted zucchini, sliced steak, seared shrimp, and sauerkraut.
Drizzle the maple-tahini dressing over the bowl and serve immediately.
