Hiya
I started SW doing a mix of Green and EE- I do eat meat, more often than not now, but still like to throw a Green in every now and again.
It's the same as SW for meat eaters really- just replace the meat with Quorn or vegetable alternatives.
If you eat no meat or fish at all you can have 2 HexA's (milk/cheese portion) and 2 HexB's (bread/cereal portion) each day.
Some breakfast ideas: Poached eggs and tomatoes on toast, porridge with fruit, cereal/fruit, mixed veg omlette, Quorn English breakfast.
Lunch: Jacket potato with beans/cheese/vegetarian chilli/cottage cheese, SW quiche and salad, cheese & pickle sandwich/Quorn sandwich/cucumber & Philly sandwich
Tea: Quorn/Lentil lasagne, chilli, bolognaise, cottage pie, Quorn steaks with veg/salad and new potatoes, Meat free burgers (quorn/mixed bean), macaroni cheese, cauliflower cheese & SW wedges, mixed vegetable curry, stir fry...
I could go on, but it might be better if you tell me the kind of meals you like that are already vegetarian, or the meals you liked when you ate meat, so I can tailor it a bit better!
Check out the recipe thread too- there's some veggie stuff, ideas for breakfast/lunch/dinner and 'Delicious Meals with Minimum Ingredients' is ace!
