Am I right? When is the last time you ran across a single leek? They are always rubber-banded up with two or three of their friends, and as a result, I always seem to have an extra leek or two in my fridge. Which is very handy when I get a craving for this sandwich.
Anyway, slice the white and light green section of a leek into halves lengthwise and rinse it thoroughly, Now slice it up and saute it in a little olive oil until it is soft and the edges are getting crispy.
You are now in the home stretch! Slice a couple of nice soft rolls in half and slather the bottom with Boursin cheese (I like the herb and garlic variety for this, but the peppered kind would also be scrumptious). Layer on some rare thin-sliced roast beef and top it all with a spoonful of those warm leeks. And…you are done! Supper is ready. And I promise you that this sandwich and a glass of red wine is all you need to perk up your evening when you come home feeling like this…
