I actually thought this was a really nice summation of good thrifty food shopping habits. They left out some tips like sensible stockpiling and utilizing sales responsibly, but it's hard to truly cover everything in any single article.
I implemented 3-5 by using a pie crust (dough) leftover from thanksgiving and wrapping it around a piece of cod I bought on manager's special. I used a mix of on hand seasonings, pepper, parsley, onion powder, garlic powder, a bay leaf (crumbled it). Baked it all at 400 degrees for 15 minutes (about 5 minutes longer than the suggested cooking time for the fish). It came out very delicious.
I wasn't following any specific recipe, just made some approximations based on cooking instructions for the fish and the dough.
