I have now been on Green days for 10 days, and because I never use Quorn or tvp, have had to be inventive with all my vegetarian options whilst keeping things simple.
I use potatoes at breakfast time in a sort of frittata: eggs, boiled potato cubes, and choose mushrooms, onions, green beans, kidney beans, red and green peppers, sprigs of broccoli, aubergine etc. some of which are usually last night's leftovers. It's filling and syn free, now I've discovered fry light spray - the olive oil one seems to taste no different but is more expensive.
Dinner is rice, cous cous or pasta/rice or egg noodles, with a heap of steamed vegetables and pulses such as chick peas/kidney beans/baked beans (versatile if sauce is washed off!). I vary them according to whether I want the dish to taste European, Arabic, Indian or Far Eastern. Sometimes some grated cheese finds its way in, but I miss my cheese so much I very often use permitted whole wheat crackers such as ww Crackerbread, with slivers of cheese, as an a+b healthy option finish to the meal. I am avoiding bread, as there are too many risks associated with it i.e. what one puts on it! Lunch is easy. I make plain Instant noodles every day at the office, and eat them with salad vegetables, or plain, followed by plenty of fruit.
