It's funny- while completely understood, I went the other way...My Parent'(parent for most of it as my mom passed when I was 10) were far from rich and menus were very limited. Because of that, my palate went the way of wanting to explore foods and tastes. If I were single- my weekly bill would be pretty high. Being married, we tend to do Salads at least 3-4 times a week for dinner. Though, we do try to have some proteins with it and the wife makes up a homemade dressing. Though, when she cooks, it is usually special with her Caribbean roots, the flavors and spices are out of this world. She also cooks for 10 even if it is just the two of us so there are always left overs. Many times- we portion out the left overs and freeze them.
So- it keeps our costs way down. And being Caribbean, even when we get chicken, it is never breasts it is usually thighs, legs, backs, etc...much lesser costs and much better flavor. And outside of grilling season, red meats are usually stew meats so again, cuts down on costs.
Where we splurge is on fish. Whole Red Snapper(head on) and Salmon are usually our two staples. And then for special occasions- meat products like Oxtail and Goat are on top of the list and both pretty expensive.
