Hi chilli,
Try this site and go to the questions and answers for some help. There is one there about peanut butter,

Try one slice of bread, scrambled/boiled egg and tomatoes/mushrooms
30gms. porridge with flaked almonds, seeds and berries/stewed apple and cinnamon. seeds and nuts.
If you like fish then try some with a small piece of bread and some mushrooms.
You will see that these breakfasts are balanced with all food groups and are low G.I.
Make a large pot of soup using chicken, veggies and stock and pearl barley or some mixed beans and don't include any bread when you eat it as the pearl barley and beans are in place of the bread and are slow release carbs and you will feel fuller for longer. Make enough so that you can freeze some portions and this means there will always be something for you to eat. Finish off with a yoghurt.
Main meal include plenty of veggies, lean protein and substitute potatoes for sweet potatoes, use basmati rice or wholemeal pasta. You only need 30-40gms of the carb part so make sure there are plenty of veggies and include a side salad if approriate. Finish off with some low G.I. fruit.
Although these meals are low G.I. you will still have to test to make sure that they are alright for you personally. It is all about testing. You may find that some of the carb foods raise your blood sugars and then you need to halve them and see the response. If that doesn't work then cut them out completely and substitute with one that tests alright for you.
The key points are testing and balanced meals. G.I. is difficult if you do not balance the meal.
Hope this is of some help.
Catherine.
