1/2 sheet of Dufour Puff Pastry (This is THE BEST Puff Pastry, a little more expensive, but sooooo worth it).
2 medium yellow onions, sliced in half moons
1 bunch red chard, roughly chopped
4 slices swiss cheese
1 Tbsp olive oil
1 Tbsp canola oil
salt and pepper to taste
Preheat your oven to 375 degrees. Oil a cookie sheet, or the foil on top of one and place your puff pastry on it. Toss it into the oven and bake for 30 to 35 minutes until it starts to get golden brown. While its baking put a frying pan on medium heat, add the oil and onions and stir occasionally until caramelized, about 20 minutes. Add the chard and season. Continue to stir until the chard is wilted, about 5 to 7 minutes. By now your pastry is baked. Layer the chard and onion mixture on top, cover with cheese and return to the oven. Bake until cheese is melted, about 7 to 8 minutes. Now get your grub on.
