Heat a deep pot or Dutch oven over medium-high heat. Add the oil, two turns of the pan, to the pot. Add the ground turkey and brown and crumble with a spoon or potato masher. Add the salt, pepper, chili powder, cumin and coriander; stir to toast the spices. Add the onion, peppers, garlic, zucchini and jalapeños; partially cover and cook to soften, 8-10 minutes, stirring occasionally. Add the beans, corn, tomatoes and stock and bring to a bubble. Simmer until ready to serve. Season with hot sauce, to taste.
