Start by peeling, rinsing, and dicing up the potato into small bite size pieces. Place in a pot with a splash of oil and water. Bring to a boil and let it cook for 5-8 minutes.
While potatoes are cooking add butter to skillet on stove and add diced onions. Sauté for 4-5 minutes. Then you will add in the ham, evaporated milk, seasoning, and cheese.
Lower the heat to a simmer and let the sauce cook as the potatoes are cooking. In a bowl you want to add your flour, baking powder, and salt. Mix. Then create a well in the center.
