Hi Petey
I will try and think but might have to add stuff later.
A steamer of some kind is a good idea, it is a great way to cook food. I do have an electric tefal steamer which I have had for several years and totally love it, I use it all the time. You can do a whole meal in it.
Potatoes in the bottom, salmon in the middle and veg on the top. Also it catches water in a tray that drips from the food so you can use that to add to gravies and sauces.
It is this one
Hanna and Browne-Kitchen Appliances-Steamers-Tefal 3 Tier Aquatimer White Steamer.
They baskets stack on top of each other for cooking, and then they sit inside each other for storage, so it doesn't take up too much room.
I would highly recommend it if you want one like this.
However you don't need to buy something like that, you can get steamer saucepans like this
Fix and Mend
or just a steamer insert that will go in your existing saucepan like this one
SKK Tri-Ply Steamer Insert () - Armorica Online Cookshop - cookware, kitchenware, and kitchen equipment
that one looks a bit expensive, I got my sister one of these for about £3 in tesco.
If you you don't have one already, a blender of some kind for making soups and other things like houmous, or smoothies.
You are encouraged to use a lot of herbs and spices to flavour food (especially instead of salt). You might want to start stocking up on those. I used to use them quite a bit, but now use them a lot. You can have them from day 3.
