OK, so it's not really zucchini boats, it's Acorn Squash Boats. They are very similar but a very different experience. Start with a medium sized acorn squash. You will need one half for each person you are serving. Cut in half and dig out all the seeds. Brush flesh with olive oil, then salt and pepper. Place on a cookie sheet, cut side down and bake at 400 degrees for about 40 minutes. The flesh should be starting to caramelize.
In the meantime, take one leek, cleaned thoroughly, then chopped. Put it in a saute pan with about 2 Tablespoons of olive oil. Add about half a pound of sausage, crumble and cook. Add salt and pepper, and herbs if you wish.
You want to cook this mixture thoroughly because it is not going back into the oven. Make sure the mixture is not too liquidy, it should just start to brown and the pan should be dry of liquid.
When sausage mixture is done, mix in about 1/2 cup of feta cheese. Take squash out of the oven and invert one half onto each plate then fill with the sausage mixture. YUMMY!
