Yep you can do this and have rice and do it every day if you wanted to. Although you might get a bit fed up of curry!
But remember, you can only have one HEXa and one HEXb if you do this.
And yep, you can do this just for one day or every day if you want. It's like red days and green days: you can swap between them as much as you want.
I like the idea of doing Extra Easy every now and again for stuff for this, but I miss by HEXs way too much to do it every day. I can't choose between cheese and milk and I can't cope without bran flakes in the morning and a HiFi bar later on!
Enjoy your curry!
