The amazingly creamy pasta sauce is made with butter beans! It's blended with pasta water, red pepper flakes, and garlic, so this dish is packed with spice and flavor!
Add red pepper flakes, chopped oregano, & beans and stir for 3 more minutes.
Taste and adjust salt as needed. Set aside the bean mixture to cool. In the meantime, cook pasta.
Drain the pasta in a colander, reserve pasta water. Place bean sauce in large saucepan. Add the cooked pasta along with ½ cup of the starchy water. Mix well to combine.
Bring to a gentle simmer & add peas. Stir for 5 minutes, cooking at low to low-medium heat until sauce thickens slightly.
Stir in lemon juice & lemon zest just before serving.
