24 ounces ditalini or other small pasta
1 1/2 cups mayo
When the pasta is tender—cook a little bit softer than al dente for cold macaroni salad, otherwise it's too firm—drain, preserving the water. Bring the hot pasta water back to boiling, then cook the corn and peas for about 3 minutes. Chill the pasta with ice (otherwise, it will melt the cheese). Chill the corn and peas in the same way. Stir all ingedients together carefully (if you are too rough the avocado will turn into guacamole), then add the dressing and mix. Adjust seasonings as necessary. Chill till serving. Or eat some slightly-warm for lunch.
