Cook the pancetta. Heat a medium non-stick skillet over medium-low heat. Add pancetta and cook for 7-9 minutes, until pancetta is crisp. Drain on a plate lined with a paper towel.
Cook the peas. Place the peas in a small microwave-safe bowl. Add 2 tablespoons of water. Cover with a paper towel and microwave on high for 1 minute. Stir and cook for an additional 30 seconds.
Boil the pasta. While the pancetta is cooking bring a large pot of water to a boil. Add the pasta and cook for 6-7 minutes, until pasta is al dente. Drain, reserving ½ cup of the pasta water.
Create the sauce. Pour the pasta back into the pot and place back on the stove, which should still be warm. Add the cheeses, yogurt and peas. Stir to combine. Add the pasta water and continue stirring until the cheeses melt and a creamy sauce forms.
Serve. Divide pasta between 2 or 3 bowls, top with pancetta and serve immediately.
