Split Pea Parmesan Spread

A favorite of mine from _Laurel's Kitchen_ is split-pea parmesan
spread.  I made it last night and think I can quote it from memory:

1 c. cooked split peas
2 T. mayonnaise
2 T. Parmesan cheese
2 T. cottage cheese
1/2 t. salt
1/4 t. dried, crumbled basil (or use more fresh)

It looks and tastes nice on store-bought black rye that they call
pumpernickel.  I usually substitute more cottage cheese for less mayo
plus I just tried "fat-free cholestoral-free mayo" but I must admit the
best version is the original.  The "wonder-what-it-is mayo" just didn't
add the right tang.
