Heat 1 tsp olive oil in a large pan over medium heat. Add garlic and sage and cook a few minutes until fragrant. 

Add pumpkin, almond milk, salt and pepper and stir until combined. Bring to a simmer then lower heat, stirring occasionally. 

Meanwhile, cook pasta according to package instructions. 

Add sauce to cooked pasta and wash pan. Heat 1 tbsp of oil in pan to medium heat. If a sage leaf simmers when it touches the oil, it's hot enough. 

Fry the sage leaves for about a minute on each side until crispy. Drain on a paper towel. 

Serve pasta with two fried sage leaves and parmesan if desired.
