I followed the "Chard and New Potato Curry" recipe in the River Cottage Veg cookbook. I substituted spinach and used regular russets and added a bit of cubed tofu. And also instead of yogurt I substituted almond milk. I kept all the spices: garlic, ginger, garam masala, mustard seeds, turmeric etc the same. Delicious!
This curry goes well with rice, couscous, quinoa or chapati.
