Once the cooler weather arrives, I just love cooking with pumpkins and squashes.  This is a twist on the Greek dish, Spanakopita but has the addition of roasted butternut squash and pine nuts to add sweetness, along with the spinach and feta cheese. So good!!
You can also add sweet potato instead of the squash and replace the dill with other chopped herbs, like parsley or basil or use sun dried tomatoes, or some diced bacon with the onion. If you don’t like feta cheese, try parmesan or mozzarella or even a blue cheese.

6 sheets filo (phyllo) pastry, thawed
2 cups peeled, diced small butternut squash
5 tbsp extra virgin olive oil
1 onion, finely chopped
1 bunch fresh spinach (around 8 oz) stems removed, chopped
1 tbsp finely chopped fresh dill
1/2 tsp salt
1/4 tsp freshly ground black pepper
4 oz feta cheese, crumbled
1 tbsp melted butter
2 tbsp raw pine nuts

Preheat the oven to 350 F
Toss the diced squash with 1 tbsp of olive oil, place in a single layer on a baking tray and cook for 15 minutes.
While the squash bakes, heat 2 tbsp olive oil in a frying pan over a medium heat.
Cook the onion for 6 minutes, then add the spinach and cook for 4 minutes, stirring regularly.
Stir in the dill, salt and pepper and remove from the heat.
Stir in the crumbled feta and baked squash (keep the oven heated to 350 F) and set aside.
Combine the remaining 2 tbsp olive oil with the melted butter in a small bowl.
Place 2 filo sheets side by side on a work surface and brush each sheet evenly with the butter-oil mixture.
Place 2 more sheets on top and brush with butter-oil, then repeat once more.
Cut each stack into six 5 inch squares, for a total of 12 stacks with 3 sheets each.
Lightly grease a standard 12 cup muffin pan with butter-oil mixture.
Place each square filo stack into a muffin cup, pressing gently to mould the pastry into the bottom.
Spoon 1/4 cup of the spinach-pumpkin filling into each and fold the extra pastry back over the filling, roughly crumpling around the edges so that the filling is still exposed.
Brush the edges with the remaining butter-oil mix.
Sprinkle pine nuts in the middle of each tart.
Bake for 18 minutes, then remove from the oven and transfer the tarts from the muffin pan to a cooling rack.
Let cool slightly then serve.

Variation ; Instead of making 12 muffin-size tarts, you can make four individual pie-sized tarts or one larger pie
