Rub pork with cajun seasoning and some salt (if needed, depending on how salty your cajun seasoning is).

Heat oil in a large skillet over medium-high heat. Add onion and jalapeno and cook until tender, about 2 minutes. Push mixture over to one side of the skillet.

Add the pork chops to the open side of the skillet. Cook 3 minutes on each side until browned.

Add canned tomatoes to the skillet and stir, incorporating with the onion/jalapeno mixture. Bring to a simmer, reduce heat to low and cover. Cook for 6-8 minutes until pork is no longer pink inside.

Serve pork chops with sauce spooned on top.
