Prepare and blanch the peppers: Cut the tops off of the peppers and rinse out the seeds and veins, handling the peppers gently. Make sure each pepper is able to stand up straight; if any do not, cut a thin slice off the bottom of the pepper— being careful not to create a hole—so that it will be stable.
Prepare the filling: Sautee the ground beef with the onion in a skillet over medium heat, breaking up clumps as much as possible as you go, until the meat is all brown and the onions have softened. Drain any excess fat.
Add one can of the tomato or pasta sauce, corn kernels, chopped celery, bouillon powder or paste, oregano, and cumin. Cook, stirring occasionally, for about 10 minutes so that flavors will meld.
Stuff and bake your peppers: Spoon filling into each pepper, packing it down gently, until it is full. (If you end up with any extra filling, save it for another use.) Place the stuffed peppers into a large baking dish. Mix the second can of tomato/pasta sauce with a ¼ cup of water; place a spoonful of this mixture on the top of each pepper. Pour the remaining sauce in the baking dish around the peppers.
Serve your delicious stuffed green peppers hot. Refrigerate or freeze any leftovers.
To reheat a refrigerated or (thawed) frozen pepper, cut it in half longwise and place both halves, filling side up, on a microwaveable plate. Microwave until hot.
You don’t really need to prepare any sides to go with this dish, but if you find you must have something else with it, I’ve found that some (not too dry) refried beans work really well. Their smooth texture is a nice contrast from the meat and rice filling, and the flavors are complementary.
