To begin, start your salted water for your pasta. Slice your sausages into 1/4 inch slices.
Saute them in a skillet until browned. Turn off the heat.
Meanwhile cook your pasta according to package directions. Half way through the cooking, add in your frozen peas.
Drain when the pasta is done cooking. With a slotted spoon, scoop the sausages from the skillet and combine with your peas & pasta in a serving bowl. Stir in the basil pesto.
