Bread crumbs? Really? I don't make my own, because I use all my bread. I don't consider using then semi. And I do use canned tomatoes; puree, paste, stewed & sauce and still consider that homemade too. I don't make/grow all my own spices either. To me that's the same as the breadcrumbs.
The only boxed thing I think I use is Betty Crocker Au Gratin Potatoes, with homemade meat and veggies. So 1/3 bought, 2/3 homemade. I use them in place of noodles, rice or potatoes when the meat I make doesn't have enough juice for gravy. Like breaded, fried fish or porkchops or chicken cutlets. Everyone loves them and makes mealtime short prep.
