I'm looking forward to seeing what other people have to say and getting some good ideas!!
We are a family of 5 with 3 DC's ranging from 5 to 10 months. Most of our fruit, veg and meat is organic but rice, noodles, jars of stuff etc is not. I used to be a vegetarian but we all eat meat now so manage to have a few meat free meals a week.
We buy organic food in bulk from Suma (though Infinity in the South is better!). We also find local organic farms have much cheaper veg than shops / delivery. Eg 20Kg bag of organic potatoes for £10!!
Abel and Cole frequently do an "organic on a budget" article on their leaflet - Couldn't find online in a 30 second search, but you could ask them.
Contraversial but organic meat tends to be better even if more expensive so you possibly need less - eg, I put loads of veg in sheperds pie, risotto, stews etc.
If you need to think about deciding between organic and non organic, think about what motivates you to choose organic and base your decisions on that, eg animal welfare - some "happy meat" farmers only give antibiotics when required rather than routinely so could be a good compromise, inorganic residues are lower in some foods than others and some foods are not a big part of your diet - eg herbs etc. If it's an environmental driver, organic food shipped from the other side of the world may not be better than non organic grown down the road. And some might be a "no compromise", some nutritionists say that if you do one thing it should be milk, others say meat and for me it's unsulphured dried fruit! Fish is tricky as organic = farmed and I'm not sure where on the moral highground that fits compared to poached on the neighbouring organically farmed estate?
Some typical meals:
Noodle soup
Roast chicken (with chicken stew and stock for the freezer)
Rice, fish and veg
Puy lentils (with veg, bacon and grated apple) goes down a lot better than it should given how "earthy" it looks!!
Tofu, veg and noodles.
Sheperds pie
Pasta and vegetables
Happy meat (not organic) sausages, mash and peas
Homemade Fish fingers ("happy fish" - not cheaper than shop bought!!)
