My desperate psychological need to feed people makes me obsessive over whether or not my friends and family eat breakfast.  I know there are other things and meal to obsess over but I just can’t get over the fact that some people should be eating breakfast.  My concern grew so great that in my previous jobs, I used to have a small breakfast delivery business where I catered meals to my colleagues every working morning, delivered hot on their desk.  Those days are over though as making hot breakfasts from scratch 5 days a week for 3-4 people is just not feasible anymore now that I have a baby who tends to get very active around 5:30 AM.


Still, I am concerned whether or not my husband feeds himself in the morning otherwise his coworkers run the risk of experiencing his hunger grump.  So, instead of getting up early to make something, package it and send it off for him, I just make these breakfast pastries.

I dare him to refuse this pastry inspired by the British classic of mushrooms on toast.  This portable pastry of buttery puff pastry wrapped around bacon, scallions, shallots and mushrooms then topped with melted cheese is deliciously simple and easy to make. Not to mention, they are also perfect for brunch or anything other time when you want to impress. That is..if you are willing to share and not eat them all yourself which, let’s be honest, is quite tempting.
