I am not vegetarian,but the best things I did lately are vegetable juices,brown rice,oatmeal,drinking water,but sometimes I still crave pizza,burgers and chocolate.
My juice is broccoli,carrots,tomatoes,spinach sometimes wild cabbage + water and honey.
I drink a huge glass of water in the morning,then I microwave oats with honey and a bit of water,idea came from Jon Fitch.
I also eat mixed nuts with sunflower and pumpking seeds,papaya and kiwi.
All this actually gave a lot of stamina,I lost 3 kg really fast,which I gained later with junk food.
