*We have a left over night once a week.
*I also make soup from whatever veggies are left in the fridge.
*Freeze left over fruit (berries, bananas) or make them into a puree for porridge (apples, pears).
*My advice would be not to stock up. I have run down my cupboards and freezer and my shopping bill has been nothing over the past month. Avoid 3 for 2 and some offers unless it is on your list. It is not a bargain buy if you don't need it.
*It was poor stock control and I literally had hundreds of pounds in my cupboards. I have a full freezer, but it is of meals made from doubling up, frozen fruit and muffins that I have made with frozen fruit.
*You don't need to stick to recipes. I have made loads of muffins with all kinds of scrag ends of sugar bags in my cupboard. It doesn't matter if you use brown caster suggest, with white granulated sugar and a bit of golden syrup. It all tastes the same, maybe better. Keep your cupboards under very tight control.
*You don't need fancy skin care. I am in my 50's and my skin is really good, so I am told. If I hit 16, and put Astral or Nivea, or Vaseline on my face every day of my life, my skin would probably be better than with the 00000000's I've spent on Clarins, Clinique, La Mer etc. Beauty products are a scam. They are basically very clever marketing people taping into women insecurities. Of course, if you have a skin issue, you need to see a doctor.
