Awwww its hard.. my DD1 has an allergy to cows milk, and my DD2 was intolerant to cows milk for 3 years and is still intolerant to soy. I breastfed for 18 months and that meant no cows milk or soy milk.

For breakfast, I guess the issues with bread is the seseme, how about some sourdough bread? Or something that would only be used on the same machines? Traces is different than containing products. Did that make sense?

I would go to things like fruit and crumpets, etc etc.... go towards using things like nuttlex (a butter alternative) which is dairy free, egg free, and sesame free.

Invest in a bread maker, I think with a permanent sesame allergy you need to be prepared for the long term.

As far as lunches go... you will have to decide how to go about it. Cheese is out, so you can have ham and avocado sandwiches, or ham and tomato. Pasta with sauce without cheese.... make some stir fry and pack that for lunch?

I don't have cheese or cows milk for 90% of my diet now as its something I've gotten used too. I think in my journey I found that cooking whole foods and larger quantities was the way to go. Do a huge roast and then use the meat and potatoes for lunches etc... Do wraps instead of sandwiches. Its hard work, but you can do it and it is worthwhile! *hug*
