In a large skillet heat a drizzle of olive oil, add pine nuts. Constantly stir the pine nuts until they are roasted. DO NOT walk away from the skillet, they will burn easily. Set the nuts aside.
In the same skillet add heavy cream, half & half and pesto, bring mixture to a gentle boil. Season sauce with 1/2 tsp of salt. Turn the heat down just a bit.
Add cooked pasta and pine nuts, gently stir to coat noodles. Garnish with Parmesan cheese (as little or as much as you want) and serve immediately.
