In a pan over medium heat, cook chopped bacon until crisp. Remove and set aside on paper towel. Leave 1–2 tablespoons of bacon fat in the pan.
In the same pan over medium heat, add the dry pastina to the bacon fat. Stir for 2 minutes until lightly golden.
Pour in 3.5 - 4 cups broth and stir. Bring to a simmer, and cook for 5-7 minutes, stirring often. Add more broth as needed if it looks too dry.
Stir in frozen peas during the last minute of cooking.
Once broth has absorbed and pasta is tender, you can turn off the heat then toss in a knob of butter, grated parmesan and Boursin cheese. Stir until combined.
Plate it all up and garnish with crispy bacon, more parmesan, and black pepper.
