I live alone and I usually spend 30€ for groceries weekly.
But one trip is the best, cause I tend to buy stuff I don't need if I go there often. Also meal planning is great, doesn't work for me, cause I want to make food I'm in a mood for, lol.
But one great way is to make more food at one time, like make enough food for few more days.
Also hunt some deals! If there is good deal on some product, spend a bit more that week and next week you don't have to worry or find some stuff that is on discount, buy some extra and put it in freezer so you can use it later.
Also only buy things you know you will actually use/eat, I know many who just throws away food, cause they didn't end up using it.
