I understand that sometimes eating lunch out with co workers is part of the deal so save money on the breakfast ... here is a good one pan quick breakfast I used to make in the am's for me and my hunny that took 10 min, I would start it while wating for my flat iron to heat up and my moisturizer to set ...
1 med potatoe (russet/yukon gold use 2) peeled and shredded (I like them shredded big.) - you can peel the potatoes ahead of time and store them in water but you loose some of the flavor.
beat 1 egg - 2 egg whites
4 strips of bacon
Burrito tortillas (wheat works)
In a VERY LARGE skillet 16" is what I use pour 1-2tbsp of oil and spread evenly ... add the potatoe shreds to one side of the skillet, season as you like (pepper/garlic salt is my fav), place the bacon strips on the other side of the skillet, once the potatoes are ready to flip then add the egg mixture ON TOP of the potatoes and flip them. Put the tortillas in the microwave for 20 sec then fill with the bacon strips (two each) cut the potatoes in half and fill the tortilla ... at this time you can add cheese if you like or salsa ... wrap the burrito (top and bottom then side and roll) and place the "seam" of the burritos on the hot skillet ... this creats a seal of sorts to help keep the burrito together brown the other side if desired. Practice it on the weekeds to work out the timing if needed, I would get dressed in between stages or fix the thermos' with their coffee etc ... This was a favorite of my house. You can also add bell peppers, spinach yum!, mushrooms or anything you would put in a breakfast burrito or scrambler. We both stopped spending money for breakfast/coffee and reserved it for lunch, still bringing lunch as often as possible.
