Paleo quiche

I got this recipe from eatdrinkpaleo.com.au. She has a really good 1 week Paleo meal plan where this recipe was included. I added some parma ham to our quiche, I think bacon would've been good as well.

Ingredients
serves 2-3
1 medium sweet potato, diced
1 brown onion, sliced
1 red capsicum, sliced
1 tbsp fresh thyme leaves
3 garlic cloves, finely diced
1 tbsp balsamic vinegar
pinch of sea salt
6 eggs
¼ cup full fat cream
zest of 1/2 lemon
sea salt and pepper for seasoning
1-2 tbsp of pine nuts
butter for cooking

Preheat oven to 200°C. Grease a flat baking tray with coconut oil and scatter diced sweet potato. Bake for about 20 minutes. Remove and turn the oven down to 180°C.

In a medium frying pan, sauté onion and capsicum in butter on medium heat for 15 minutes. After 10 minutes of cooking, add fresh thyme, garlic, balsamic vinegar and a pinch of salt.

Whisk the eggs with cream and combine with the zest of lemon, a pinch of black pepper and a generous pinch of sea salt. Grease the bottom of a deep baking tray with coconut oil and line with baking paper, making sure the sides are covered. Assemble sweet potatoes and onion and red peppers mix evenly on the bottom. Pour whisked egg mix on top. Bake for 10 minutes, then sprinkle with pine nuts and some extra fresh thyme and bake for a further 10 minutes. Stand aside to cool and settle for 5 minutes before serving. Lift the sides of baking paper to remove the quiche to a cutting board.
