Marjorie, I eat coconut oil straight off the spoon, but you can cook or bake with it.
I know when we are worried over something or when we are feeling below par we tend to crave our comfort foods, in your case its probably bread, butter is ok, but the carbs in bread, you need to limit those.
You are quite right there when you say that your bg levels should be lower, do try and get them down befoe the op and keep them low after the operation, you will find that you will heal quicker, and less chance of infection setting in.
Have a look in the low carb recipe forum there are some recipes for low carb breads, try them out, I regularly bake the white loaf from this site

the bread will also freeze, you can freeze in slices.
But have a look at the other recipes as well, might be worth a try, it depends what bread you eat, many people swear by Burgen Soy & Linseed loaf, maybe its a better option for you.
Anyway I hope that all is going well for you x x
