Me, too, joining as of November 1, 2015. We, family of 2 humans and 1 cat, need to reduce our expenses more, and I took a look at food spending. In January of 2013, our groceries, pet food, and eating out added up to $936 or 779/157... terrible! October of 2015, the total was $816, which is still way too high.
A problem for me has been my special diet due to digestive issues, but I am learning how to deal with it. I have been put on three different (simultaneous) diets by my docs: gluten free, low FODMAP (no beans, onions, apples; restricted mushrooms and many other fruits and veggies), and balanced PH (going for about 70% alkalizing and 30% acidifying foods, which ends up a very low carb (minimal rice, quinoa, other grains, GF bread, etc.), mostly plant-based, minimal-grains diet). When I eat what is allowed on all three diet plans, I feel pretty well. DH can and does eat anything and everything.
So, I have been reading this thread, looking to improve. I made a menu and shopping list for this week, and today I rode my bike-with-trailer to the market and brought back a week's groceries (including dish detergent, but not cat food) for $59.03. Holy cow! Thanks for all the great ideas!
Current monthly (no cat food) food spending: $624 groceries/$73 restaurants
Monthly goal for 11/15 and 12/15: $324/73
