I'm not loyal to any brand or shop. I bulk buy offers when I see them as I have 2 x 6ft chest freezers plus one above the fridge, so some weeks my shopping is nothing at all as I'll use stuff from there, but on other weeks it may be double my average weekly shop as I snap up offers when I see them.
I recently bought a 3.7kg leg of lamb for £3 along with a free range bronze turkey for £4 ( 5-6kg), lean steak mince 450g for 32p, 3 packs of 2 salmon fillet pieces for 9p each, 2 x 180g mackerel fillets at 9p each, 3 packs 8 wraps for 9p each, 2 seeded loaves for 9p each and 360g king prawn for 99p each (x 2 packs).
Everything gets portioned out where required and then frozen with best before date written clearly on the outside.
Everything in my freezers is repackaged into containers and zip lock bags and then neatly stacked and organised into different categories so that is easy to find what you need, eg, bakery, fish, seafood, meat, poultry, home-made meals, veg, etc.
I cook things like shepherd's pie, various stews and casseroles, fish pie, pasties, meat and veg pie, steamed fish, pasta, risotto, roasts, chilli, etc, and I bake my own bread. I follow a weekly meal plan based on what I've got in the freezer and apart from reduced items, which I buy when I see, I stick to a shopping list.
Breakfast is generally porridge oats or another cereal made with water or milk and served with small handful of fresh fruit (eg, few grapes, few segments of tangerine, a couple of raspberries or whatever was on offer).
On the weekends it might be toast with scrambled/poached eggs or for something special: bagels with cream cheese and smoked salmon.
Lunch for dc is 1 round of sandwiches with ham or cheese, etc, small fruit juice, 1 or 2 pieces of fruit/salad veg, 1 individual treat eg, 20g pack mini fingers or 1 gold bar, etc (snacks vary according to what was on offer) and maybe a chunk of cheese. Plus they take a homemade flapjack or something for a snack.
Dinner is homemade. Meat portion is around 150g per person, sometimes a bit more (eg, when a steak or slices of roast meat), sometimes much less (eg, when in a stew). I make my own basic sauce, etc, in bulk and freeze them in portions that are enough for 2 and I add different ingredients to them after defrosting to make different things, eg, bolognese, chilli, arrabiata, etc.
The DC have a snack after school which usually consists of 1 slice toast and jam. We don't always have dessert but when we do it's either homemade (eg, sticky toffee pud) or a yoghurt.
