In a large skillet, heat 1 tablespoon extra virgin olive oil over medium heat. Add ground turkey and cook until browned. Approximately 5 minutes.
Add onion and cook until onion is translucent, about 5 minutes.
Add garlic to pan and cook another few minutes.
Transfer meat mixture to a large crock pot or a Dutch oven.
If using a crock pot, turn on high to cook for three to four hours, or on low to cook six to eight hours. On the stove, if using a Dutch oven, cook over medium heat, then reduce to low once it starts to bubble.
Add cumin and salt to pot.
Drain all three cans of beans in a colander and rinse thoroughly to remove all the starch, sodium, and sauce.
Add drained beans to the pot and cover.
Cook desired length of time.
Serve with sour cream, cheddar cheese, and jalapenos if desired.
Remember, this is always better the second day if you can wait that long to eat it!
