I make a huge batch of spag bol at the weekend and halve it, make one half into chilli. And then back up the bol and the chilli into freezer bags and pop in freezer. (I also make it in the slow cooker so once it’s on I can get on with making:
home made fish fingers in shredding coconut (again, I buy more than needed and put most in the freezer to pull out quickly and cook from frozen)
sausage and bean casserole (grill off sausages, chop up and add to pan of chopped onion garlic tin of chopped toms and tin of mixed beans in spicy/taco sauce. Half and put half in freezer for next time
basically anything I make I buy enough to make at least 3 meals for the 3 of us at once and shove the rest in the freezer. Other things include: curries, boursan chicken, shepherds pie, meat balls, vegi tomatoe sauce (to add bacon and pour over pasta).
we don’t do separate toddler meals, we all eat together. Other quick meals we do is baked salmon and chips, pitta pizzas, tortellini, fajitas, sweet potato tacos
I recommend the what mummy makes books for family meal ideas that are quick and bulk made/freezer friendly
