This is one of my kids' favorite dinners and you can make the whole thing in the time it takes to cook the pasta. I buy smoked salmon in the refrigerated section of the grocery store so I can have the ingredients waiting in the fridge anytime...if you cannot find it you can also use leftover salmon, or roast an 8 ounce fillet in a 450 degree oven until cooked through - about 10 minutes. Bring a pot of water to a boil, add salt and pasta, and cook until al dente. In the meantime, chop a small onion and saute in olive oil. Add a bag of frozen peas, and a pint of half and half. Break 8 ounces of smoked salmon into little pieces and stir into pan with cream and peas. Simmer until heated through. Drain pasta, return to pot, and toss with salmon mixture. Season with a little salt and freshly ground pepper and serve.
