Add the mixed greens to a bowl and top with shredded carrots, sliced red cabbage, red pepper, chickpeas, feta, pickled red onions, sunflower seeds, and pumpkin seeds.
For the dressing, add the tahini, lemon juice, honey or maple syrup, minced garlic, salt, pepper, and olive oil to a mason jar. Shake until smooth and fully combined.
Drizzle over the salad just before serving and toss everything together until coated.
