Not many photos but made this for my parents for lunch and it went down a storm
Begin with the onions. Take about 8 onions (I used red and brown) and slice. Melt about 50g of butter in a pan and add the onions and stir to coat. Then cover for 10 minutes. After this uncover and add a teaspoon of brown sugar and cook slowly for about another 20-30 minutes so they are soft and sticky but not burning.
Get a packet of filo pastry. I have recently discovered JR Feuilles de Filo Pastry which is fantastic and really easy to work with.
Take one sheet at a time and either use melted butter to coat or spray oil to keep the calories low. Lay into a pie die and scrunch in the sides a bit so there is not much ovelap. Repeat with about half the pack. Mix together the onion mix with a bag of baby spinach and cover the pastry with this. Then drizzle with some balsamic vinegar and slices of goats cheese. Finally take the remaining pieces and again spray with oil or butter and scrunch loosely into large balls and cover the surface roughly.
Bake at 180 degrees for about 20 minutes until it is golden and crisp. Serve with buttered new potatoes, homemade coleslaw and a green salad. Delicious and actually not very high in calories.
