Step 1

Bring a large pot of salted water to a boil, and cook pasta as instructed on the box or bag. Add peas to the pasta water, during the last minute of cooking. Reserve the pasta water.

Step 2

Meanwhile, heat olive oil in a medium-sized deep skillet over medium-high heat.

Step 3

Add onions, garlic, and a pinch of salt and cook until translucent, about 3 mins, stirring constantly.

Step 4

Stir in beans, and cook until heated, about 3 mins.

Step 5

Transfer everything to a blender along with soy milk, miso, lemon juice, and nutritional yeast. Blend until smooth and creamy. Add more soy milk if required to get a thick but pourable sauce. Taste and season with salt and pepper.

Step 6

Transfer the sauce back into the skillet, and add pasta, peas, and a bit of the pasta water.

Step 7

Cook stirring constantly, until the sauce clings to the pasta, and everything is evenly coated, adding more starchy water as required.
