I tend to eat a big bowl of oatmeal during the week, as well. I like to make it with soya milk and put chopped up dates in it to sweeten it without any added sugar. When it's not oats, then it's some kind of cereal (preferably whole grain).
My all time favourite breakfast foods are eggs and bacon and begian waffles.
I do like to eat breakfast foods for other meals (especially for tea).
And, I have changed some of what I eat since moving to the UK. I don't eat as much dairy (so I use soya on my cereal or in my oats), and, where as I used to sleep through breakfast, now I have to be up for work, so I like to eat a good, hearty breakfast that will keep me going through the morning.
I, too, used to enjoy going out for breakfast in the US. The closest thing I get to it here is going out for coffee and a bagel with smoked salmon and cream cheese on Saturday mornings sometimes.
