Ok, chop them washed leeks up. Get all the dirt out. Now mix the seasonings (sans oil) and put that in a reclosable baggie. Shake'em up and down (or side to side if you prefer). Add a drizzle of olive oil to a pan and either fry them tender, or bake at 350 degrees for 20 mins. Dont let them get cold or the magic leeks out!
Suitable as a side dish to anything that would be complemented by onions. Nice little 'knosh' all by themselves on a late night for a dieter.
