In a medium to large pot, heat the oil.
Add the diced onion and serrano chili. Saute on medium heat, until the onion is soft and translucent.
Add Sukhi’s Classic Curry and mix well.
Add tomatoes, potatoes, cilantro, carrots, and water. Reduce the mixture over 10-15 minutes or until the vegetables start to soften.
Use a hand masher or immersion blender to mash the ingredients in the pan. Leave it semi-chunky for best results.
Add butter, salt, and lemon juice, mix well, and remove from heat.
Add butter to a flat pan or skillet and lightly toast the buns.
To serve, add about 2 oz or ¼ cup filling to each bun.
