Fillo Tart with Cauliflower, Leeks, and Gruyere

I made this tonight in Thomas's fancy kitchen, and it was awesome.

2 leeks, chopped
1 head cauliflower, chopped
1 head romanesco, chopped
1 jalapeño, chopped
frozen puff pastry
butter and egg for brushing
salt and pepper to taste
a good amount of gruyere

preheat oven to 400
saute leeks in butter until soft.
add cauliflower, romanesco, and jalapeño- cook until al dente. season to taste.
spread out fillo- brush each layer with melted butter- I used 6 layers on the bottom.
put cauliflower/leek mixture on fillo dough on a baking sheet.
top with abou6 6 more layers of fillo. brush top with egg wash.

bake for about 30 minutes, until cheese is oozing and fillo is golden brown and crispy!
