A bag of spinach and a can of salmon are all that stands between you and a healthy, easy weeknight dinner.
Bring a large pot of salted water to a boil. Cook boil-in-bag creamed spinach according to package directions; remove bag to a plate. Add fettuccini, and cook according to package directions. Drain, reserving 1 cup pasta water.
Turn off stove and return pot to stovetop. Add creamed spinach (discard bag) and heavy cream and stir to combine. Add fettuccini and stir, adding reserved pasta water 2 tablespoons at a time, if necessary, until spinach sauce fully coats pasta.
