Bring a large pot of salted water to a boil and cook spaghetti for 1 minute less than package directions, just until barely al dente.
While pasta is cooking, heat the oil in a large skillet over medium high heat. Add the shrimp, season with salt and pepper, and cook for 1-2 minutes per side, until just barely pink, but not cooked through. Add the cream, basil, spinach, and avocado, bring cream to a boil, then turn the heat off. Add the cheese and cover off the heat until the pasta is cooked.
Drain the pasta, add it to the skillet, turn the heat to high and bring the sauce to a slight bubble, stirring gently to combine ingredients and wilt the greens.
