Carole,
I'm pretty new at it so someone might be along to correct but:
2 Small Oranges (like satsuma/clementine) is about 10g
Bacon and Eggs is about 1g (if used milk for scrambled eggs and)
Chicken is nothing, cauliflower is about 2g and brocolli 1g (depending on portions obviously). Potatoes I reckon about 15g for 3 potatoes but if tiny maybe less.
The crackerbread I would check the pack as they vary a lot but the ones I have are 7g and cheese is normally nothing but I've not ever looked at cambazola.
So I reckon assuming no drinks that would influence it about 36g-40g carbs on that eating day.
Good luck on the testing when you start it. With carb control like that a touch of metformin you'll be smashing it in no time I'm sure!
