This is one of my favorite recipes. Not the healthiest recipe in the universe, but it's much better than most seafood pastas that are drowning in thick sauces...
1 Lg. red onion
Bundle of green onions
Alfredo powder (I use Simply Organic)
1 stick Butter
Saute onions in a bit of butter until they are soft. In a large, deep pan -- mix onions, stick of butter, mushrooms, and fish on low heat.
Add white wine and cream until you get a good consistency. Add alfredo powder to thicken it up a bit and add flavor. Add tomatoes and lemon juice.
Cook on low, covered until shrimp is pink and scallops are white. Add garlic salt to taste. Enjoy over linguini. Feel free to add other veggies... shredded carrots, yellow peppers, asparagus, and zucchini all work well... Get creative.
Garnish with fresh parsley and shredded parm cheese.
