Warm the olive oil in a wide sauté pan over medium heat. After 90 seconds, when the oil is hot, add the diced onion, poblano, and jalapeño. Cook over medium heat for 5-6 minutes, stirring occasionally, until the onions and peppers are softened.
Add the garlic, cumin seeds, oregano, smoked paprika, cinnamon, and black pepper. Stir and cook for 1 minute to bloom the spices.
Add the corn, cilantro, diced tomatoes, zucchini, salt, lime juice, and water. Stir well to combine.
Cover and cook over medium heat for 10–12 minutes, stirring occasionally, until the zucchini is just tender and the mixture is saucy.
Uncover, give the contents of the pan a stir, and sprinkle on the vegan cheddar shreds. Cook covered for 2 minutes over medium heat until the cheese is melted.
Garnish with crumbled vegan cotija, sliced jalapeño, and cilantro leaves if desired.
