Preheat oven to 400.
Spread peppers, zucchini & squash on a baking sheet. Drizzle with 1 T olive oil and season with salt, pepper and thyme. Roast about 15-20 minutes, until nicely browned. Set aside.
In a large pot, heat olive oil over medium heat. Add turkey pieces. Cook until nicely browned on both sides (about 8 minutes). Remove turkey to a plate, using a slotted spoon.
In the same pot, continue to keep over medium heat, add onions and garlic. Cook until beginning to soften (about 4 minutes).
Add cumin, chili powder, coriander, tomatoes, chicken broth and black beans. Stir to combine. Add turkey back to pot.
Bring up to a bubble and then reduce heat to low and simmer about 20 minutes until turkey is cooked through.
Add roasted vegetables and stir to combine.
