Makes 2 tarts; each serves 4-6
1 1/2 lb. Swiss chard
1 lg clove garlic, very thinly sliced
Salt & freshly ground pepper to taste
2 lg high-starch potatoes, unpeeled & scrubbed clean
3 tsp chopped fresh thyme
1 heaping C freshly grated Parmesan cheese
2 lg eggs
2 C ricotta cheese
Trim the stems from the chard, wash the leaves thoroughly, drain and dry. Coarsely chop the chard. In a large skillet, heat 2 tbps of the oil over medium heat. Add half the chard and half the garlic and cook, stirring frequently. As the chard cooks down, add the remaining chard and garlic. Season with salt and pepper. Cook for about 10 minutes, stirring until chard is just tender. Tilt the skillet to the side and blot up any excess liquid with paper towel. Let cool.
To make the crust, slice the potatoes very thinly. It's fine if some of the slices are smaller than others - the important thing is to make them fairly uniform in thickness. Create a thin layer of the potato slices on the bottom of the two pie plates (preferably glass), slightly overlapping them to create a solid bottom "crust." Gently tuck potato slices along the edges to create a border up the sides of the pie plates. When you're done, you should have two solid pie "crusts." Use thin or oddly shaped potato slices to fill in any gaps. Discard the remaining slices. Drizzle 2 Tbsp of the oil over each crust, swirling the pan slightly so the oil spreads between the potato layers and drips to the bottom. Sprinkle each crust with 1/2 tsp of thyme, some salt, and pepper, and a heaping 1/4 C of Parmesan cheese.
