This is how I plan mine a week ahead.
Sunday - always a roast or a casserole with meat or chicken portions.
Monday - pasta - but this can vary from Spag bol to pesto twists or a tuna bake or meatballs with tagliatelle but it’s always Pasta night.
Tuesday - Sausages - again a variation on the ‘theme’, sausage and mash, sausage, chips and egg, sausage hotpot, sausages, wedges and salad etc.
Wed: This is Freezer night as we’re out at ‘activities’, so it can be anything that can cook from frozen in 25 mins (including pizza).
Thursday - Spice Night - this can include, curry, chilli, stir fry, Thai, fajitas etc.
Friday - Fish. So anything from fish and chips to griddled salmon and new potatoes.
Saturday - We tend to get a Takeaway once a month but will do steaks one week, chops another, homemade kebabs another. I go to the Butchers on a Saturday and get my meat for the week.
It works well for us.
