tory I'm not so good with the meals for adults in the freezer - in the week I don't eat main meals at home and DH just eats ready meals...
However we do have bolognaise, shepherds pie, chicken casserole, fish pie and soup in our freezer as basics - whenever I make one of them I make double quantity....Also since DS, we have pizza every other week or so when we're finding it difficult. I'm not a huge fan of pizza but it is so easy!
Our freezer is mainly full of stuff for DS! I work full time so my parents look after DS and my mum cooks all his meals. She cooks 2 or 3 times a week for DS and the rest goes in the freezer and keeps us going for the rest of the time. I think that one lot of cooking keeps DS for 4 or 5 meals. Often she'll cook actual meals (like fish pie) plus some random veg (green beans or carrots) which we add as a side portion.
So, as a general rule, she cooks the food and purees it (more or less - we're starting to get into mashed food territory). Then puts it into ice cube trays, which when frozen we transfer into freezer bags. Then we defrost whatever for DS just before his meal.
We usually have for DS: fish pie (with cod), fish pie (with salmon), chicken casserole, beef stew, lentils + veg, cauliflower cheese, brocolli cheese, ratatouille with rice, peas, green beans, carrots, and various fruits purees....
For more ideas for adult food I'm sure there'll be threads on the subject on MN...it's a very common problem for mums!
