| Soften onion in butter (The more observant of you may spot a bit of stray mushroom in there too) |
| Toast some pinenuts - the recipe doesn't say toast, but frankly all nuts are better toasted I reckon |
| Mix Feta, Spinach, Balsamic vinegar, the pine nuts and the onion |
| Dollop into the middle of a scored, glazed puff pastry sheet (Don't use reduced to clear, past their best, shoved in the freezer ones...) |
| Bake and enjoy |
