Sweet Potato and Chicken Sausage Hash with Swiss Chard

0 In a large skillet (see note), heat 1 Tbsp olive oil over medium-high heat. Add sausage and saute until golden brown, 5 to 7 minutes. 
1 Add Swiss chard to chicken sausage and cook, stirring constantly, until chard is wilted, 3 to 4 minutes more. Transfer sausage and Swiss chard to a plate or bowl and return skillet to heat.
2 Reduce heat under skillet to low-medium. Add remaining 2 Tbsp olive oil and butter. Stir gently until butter melts.
3 Add potatoes in a single layer and cover with a lid.
4 Cook potatoes, covered, without stirring them, for 10 minutes. (Resist the urge to lift the lid and check them - keeping the lid closed helps them to steam and cook through until tender.)
5 Remove the lid and use a spatula to gently flip the potatoes. Scatter onions over the potatoes. Cover again and continue to cook for 10 minutes more.
6 Remove lid and stir in salt, paprika, and garlic powder. Continue cooking potatoes until they can be easily pierced with a fork (depending on the size, they may already be done or may need up to 5 minutes more). 
7 Gently fold in sausage and Swiss chard.
8 Serve warm. (Great with a fried or poached egg on top!)
