for the OP, Florence,
what would you say your main obstacles are, wrt lowering the groceries, and then, separately, lowering the eating out (which you seem to have several subcatergories of, alcohol, bars, restaurant, food & dining (?), coffee)
WRT Grocery: some possibilities I can think of:
Buying too much, not using up and throwing away (due to poor meal planning or poor scheduling)
Buying a lot of premade, processed, or packaged foods
Shopping in an expensive store
Buying premium products (bison instead of ground chuck, for ex)
Buying specialty products (boutique gelatos, for ex)
Do you not know what to make? Do you default to take out or restaurants due to ....what?
Do you need recipes? Meal planning advice? Ideas for bagged lunches or quick breakfasts?
basically, identify where the breakdown is and we can specifically offer help.
FWIW, I also struggle with food spending. I have my standards. For ex. the prudent homemaker blog writer only buys meat at 1$/lb or less and says she only buys processed hams and turkeys after holiday season. I think those hams are filled with stuff that I dont want to eat, so I wouldnt buy them. Then there are taste preferences-my family is not into beans. My kids dont eat them, and I have never been a big fan. So if people told me to live on rice and beans, its not going to happen. But there are plenty of other ways to cut back and find meals that are tasty to you and can be made affordably.
If its about convenience for you, find easy, one pot recipes or crockpot recipes. Find recipes that can be made in bulk and frozen into portions.
If its about planning, research strategies about that. When I do food planning, I take into account the weeks calendar of activities, what I have in the fridge, freezer, or pantry that needs to get used, what we ate last week, what I can afford to buy this week, etc. Once you get into it, it becomes much easier. You can institute theme nights. Soup night, Salad Night, Taco Night, Pasta night, etc. Have a night where everyone eats leftovers.
If its about recipes, well, there are tons of resources, several already posted in this thread. Pinterest can be helpful to collect and save them.
hope this helps
