Pre-heat oven to 425°F.
In a large ovenproof skillet, heat oil, over high heat, until it thins.
Stir in turkey and cook, breaking up meat with a wooden spoon, until it’s no longer pink with some browned bits; about 7 minutes.
Reduce heat to medium-high; add onion and jalapeño; cook until translucent and tender; about 5 minutes.
Stir in garlic, chili powder, 1 teaspoon salt, oregano, cumin and pepper; cook until fragrant; about 1 minute longer.
Using kitchen shears, or your hands, break up tomatoes and add them, along with the juices, to the pan.
Add beans and remaining 1/2 teaspoon salt; scrape up any brown bits on the bottom of the pan.
Reduce heat to medium-low and simmer until slightly thickened; 3 to 5 minutes.
If the mixture seems very dry, add a few tablespoons water; it should be juicy-looking but not wet.
Remove from heat and stir in cilantro; taste and add more salt, if needed.
