Heat the olive oil in a large pot over medium heat.
Add the diced onion to the pot and sauté until translucent, about 5 minutes.
Stir in the minced garlic and cook for 1-2 minutes more until fragrant.
Add chopped carrots, zucchini, and red bell pepper; cook for about 5-7 minutes until slightly softened.
Mix in the drained chickpeas, diced tomatoes, vegetable broth, cumin, and smoked paprika.
Bring the stew to a boil, then reduce heat to low to simmer for 25-30 minutes, uncovered.
Taste and season with salt and pepper as necessary; simmer for an additional 5 minutes.
Remove from heat and let sit for a few minutes before serving; garnish with fresh parsley.
