Rochelle I'm so sorry to hear this and join everyone here in wishing you a speedy recovery.
As you know, I am mobility impaired, mostly involving not being able to stay on my feet for a great length of time so I understand a lot about having to figure out different ways of doing things. Your situation is of course different from mine, but I have a few suggestions.
1) I'm sure as a professional chef/instructor and do-it-yourself home cook you are used to prepping fruits and vegetables in a way that make sense for the recipe: mincing, dicing, julienne, thin slices, and so on. Unfortunately, the last thing you need after breaking your right arm is slicing your left hand. At this point I think you'll have to concentrate on recipes that call for the kind of rough chopping and slicing one would get from a food processor.
2) Using a food processor, how about rough chopping/slicing vegetables all at once to be used throughout the week for things like soups, stews, braises, chili, etc.? After each batch of the usual suspects--onions, mushrooms, celery, carrot, fennel are chopped then hubby or someone else could put these in freezer bags (even better if you have a vacuum sealer for this) for use during the week. Since many fruits don't freeze well or hold up in the fridge for very long, use the food processor for those that do: oranges, lemons, limes and leave the peeling and slicing of other fruits that you'll be using immediately to helpers. Depending on how agile you are, you can probably take care of berries yourself.
3) As others here have suggested, the only safe recipes for you can be those that you can do safely with your left hand: stirring, some stir fry, maybe sauteeing.
I'm sure there'll be more sage advice for you here coming your way soon.
Take care.
