Pesto is the answer

I am revealing to you my trump card for every potluck or backyard bbq. Roasted russet potatoes and haricots verts with pesto. Usually I would put this over watercress. Sometimes I add capers but the pesto was a little salty this time. Why I am making it in the middle of the week on a school night when I have 42309324 pages of reading to do for tomorrow I am not sure except that it is difficult to concentrate with basil aging in the vegetable bin.
