Heat vegetable oil over medium heat. Don’t crowd the pieces, you don’t want them to stew each other.

Sear for about 3 minutes on each side.

Chop onion and add to the oil. Saute until transparent.

Put the meat in a baking dish.

Add canned tomatoes to the onions. Add seasonings.

Let the tomato mixture simmer for about 5 minutes, just long enough to dissolve the salt, then pour over the meat.

Bake at 425 for 20-30 minutes.
