vaguely conglomerated from the inter-toobs, made 28.
2 cups mashed potato (ish)
1/2 cup grated cheese (cheddar and romano)
1/4 cup grated cheese for topping (cheddar and romano)
good handful of chopped shallot greens
1/4 tsp or less paprika
small dust of cayenne pepper
Salt to taste
Preheat oven to 200C. Grease mini-muffin pan with oil. Mix it all up. Fill mini-muffin pan. Top with cheese. Bake for ~20 minutes.
Delicious straight out of the oven.
I think you could substitute different herbs / cheeses / finely diced ham or fried bacon etc. as long as you pay attention to the salt.
