If you roasted sweet potatoes ahead on Monday, this filling and deceptively simple saute will come together super fast. Avocado balances out the spice of the chorizo.
If potatoes were not made ahead on Monday, heat oven to 500F / 260C. Toss potatoes with cooking oil (portion for potatoes), paprika, and some salt and pepper. Spread out on a sheet pan. Cover tightly with foil and transfer to the oven. Steam potatoes for 10 minutes. Reduce oven temperature to 425F / 218C. Remove foil from potatoes and shake the pan. Continue roasting, shaking the pan halfway through cooking, until potatoes are tender, 15 to 25 minutes more.
Heat a large skillet over medium-high heat. Add cooking oil (portion for tacos) and then chorizo. Saute until lightly browned, 5 to 6 minutes. Drain off excess oil.
Add potatoes to chorizo and saute until potatoes are heated through.
Toss together lettuce, oranges, and pepitas. Add vinaigrette until dressed to your liking.
Serve chorizo / sweet potatoes with avocados and chives. Squeeze lime juice over top. Enjoy with salad on the side.
