Almond in any form is not on the strict diet due to possible mold.
It’s really challenging eating in restaurants but can be done if very careful.
Eggs/omelets, broiled or poached fish (no butter), salads w lemon & olive oil, steamed veggies – they are your best options for restaurants. You’ll most likely enjoy the veggies in France more because they are non-GMO.
I bake a super easy buckwheat flour soda bread. Do double check if there’s an oven where you staying because Europeans don’t have/use ovens like we do. I’d be happy to pass on the recipe.
I eat oat bran porridge every morn – 1/4 cup oat bran in 1 cup of boiling water & voila breakfast. It’s cheap & easy & light weight for travel.
Best of luck & Bon Voyage !
