We have our favourites, and I probably cook some repeat meals about twice a month.
I like to use Continental meal flavour bases. Stroganoff, Apricot chicken, pork in plum sauce, greek pita pockets etc. They are quick and easy, tho I don't always follow them exactly. I add extra vegies to bulk it out a bit. I try and make sure every meal makes at least 4 serves. I try things that I wouldn't normally try and if I don't like them I don't buy them again! Jar sauces are great too. Add meat and vege and pasta or rice. use different kinds of pasta...try gnocchi or raviolli etc to add variety.

Yes I have started to use those Maggi flavour bases... Love the beef stroganoff. Want to try it with beef mince.

I also do spagetti bolagnaise every few weeks, its easy and goes a long way.
