The star of this dish are the fresh asparagus and the light fluffy eggs. Feel free to add whatever meat or veggies you wantwp. Some of the best frittatas are very simple concoctions of whatever leftovers you can find in your fridge.
Preheat oven to 375°F
Add a tbsp of Veggie oil to a cast iron frying pan. Brown the sliced sausage. In another cast iron pan on medium heat, cook the potato and onion in Veggie oil, adding the green pepper, tomato, and lastly, the asparagus. Cook until the asparagus has just about lost its crunch. Season with all but ½ tsp of the salt.
Add the meat to the veggie mix and stir. Spread a thin layer of sour cream over top of the mixture. Then top the mixture with ½ of the grated cheese. Turn down the heat to medium low.
In a bowl, beat the eggs. Add 2 tbsp of water and ½ tsp of salt. Pour over the veggie and meat mixture in the cast iron pan. Turn heat up to medium. Allow to cook on the stove until the egg on the sides of the pan is cooked, not brown, just solid. Place pan in the 375° oven.
When the top of the egg has solidified, not browned, just solidified, remove from the oven and sprinkle the remaining grated cheese over the egg. Turn the oven to low broil, and return the pan to the oven.
When the cheese has melted and is browning nicely (about 5 minutes), remove from the oven and let sit for 5 minutes to cool and solidify a bit. Serve hot with a nice cool salad.
If you want to live dangerously, substitute the layer of sour cream for a layer of cottage cheese or ricotta.
Substitute onions for shallots for a more refined taste.
do not EVER put tofu in frittatas or any other meal!!
