I'm the same with tinned fish! I can eat tinned salmon and tuna but fresh salmon & tuna yuck! I make it for my cat sometimes and the smell turns my stomach. I like smoked mackerel but always gives me the runs, must be the high fat content.
I too have nuts to graze on and a make a smoothie using a handful of berries, banana and put complan and water in. I use complan as I don't want to get too scrawny and I also can't tolerate milk. The complan original gives the smoothie a vanilla taste. I love crackers too, I eat ryvita's with a thin scraping of butter and i like the seeded flatbreads.
You're right we could be twins as we eat pretty much the same.
Is your hubby a fisherman by trade or hobby?
