I find that Weight Watchers is a good source for recipes. I used to use ground turkey but watch when buying it as some of it has more fat than ground beef. I mostly use 90% lean ground beef. I skip all or most of the butter or oil in recipes. My family is so used to skim milk in recipes they say it tastes funny with anything else. You can add FF half and half to make things creamier. Also the American Heart Assoc and Hungry Girl are good places for inspiration. My DH has extremely high cholesterol so I have been playing with recipes for 30years. I saute veggies in sodium free chicken boullion with a little water. It actually gives them a buttery taste. Laughing cow cheese added to sauces will make them creamier.
Glad to hear you DH is doing OK. Good that he paid attention to his symptoms and went to the doctor before things got worse. Saying prayers for a full and speedy recovery.
