For boureki (μπουρέκι) you need pumpkin, zucchini, potatoes and misithra. If you don’t have misithra you can choose a goat cheese from your area that could resemble it in taste.
Slice up your ingredients and mix them all together with salt, pepper, oregano, basil and a lot of fresh mint. Do not foget to use plenty of olive oil!
Place in a pan and pour some more misithra mixed with greek yogurt and bread crumbs over it.
Let it cook in a preheated oven at 200 Celcius for about an hour until the potatoes are soft and creamy.
