I've only recently started to do the green days so no 100% sure I've got them right, or have figured out best how to use the plan, but I think I have been doing ok, without exactly being the most adventurous with my food. I've yet to do a Red day so would love to hear what you are eating sus_murf.
On green days my breakfast would usually be the same as always - either fruit salad and FF yoghurt, or weetabix with a banana and milk from my HEA, or sometimes I do the magic porridge with extra berries.
Lunches would normally involve salad and I'd have it with a vegetarian SW quiche or pasta salad etc.
Dinners could be anything from pasta in tomato sauce with lashings of reduced fat cheese, baked potato with beans, cheese & salad, superspeed soup, mixed spicy beans with rice as a kind of chilli, stuffed peppers, etc, or else if I want to have say lasagna etc I would either just have it with loads of veg or added quorn. I'm still adjusting to quorn tho. Not really 100% convinced about it.
And then some days I start out as an extra easy day to realise I only had the tiniest bit of meat or fish all day and put it down to a HEB and change to a green day. I think due to being able to have loads of potatoes, rice, pasta, couscous etc, that the green days are good too when you're a little bit broke i.e. for the week before payday!
