Shrimp
Place everything in shallow baking pan, cover with foil and place in 350°F oven for about 25 minutes. Check to make sure shrimp are cooked.
Risotto
Melt butter and EVOO in saucepan, add onion and sauté for 3 minutes. Add risotto and sauté until white. Start adding stock 2 cups at a time to start (low heat). Once liquid is absorbed add 1 cup white wine. Then slowly add more stock until rice is done, approximately 30 minutes.
Mixed Greens Topping
Using a mandolin or peeler, strip the asparagus and green onions into ribbons. Add to arugula and toss well.
