In a small pot, combine the quinoa, turmeric, cumin, oregano, and 2 cups / 480 ml of water.
Bring to a boil, then cover, reduce heat to low, and simmer for 10-15 minutes, or until all the water is absorbed.
Remove from heat and let stand, covered, for 5 minutes before fluffing with a fork.
While the quinoa cooks, prepare the dressing. On a cutting board, sprinkle the sea salt over the minced garlic. Use the flat side of a chef's knife to press and scrape the garlic and salt together, forming a smooth paste. Scrape the paste into a small bowl.
To the garlic paste, add the lemon zest, lemon juice, tahini, and vegetable broth.
Whisk vigorously until the dressing is smooth and creamy.
Assemble the bowls.
Divide the baby spinach and shredded cabbage among four bowls.
Top with the cooked quinoa, chickpeas, and a generous drizzle of the lemon tahini dressing.
Garnish with the sliced pepperoncini and serve immediately.
