This is such an easy one
, seriously, that I considered throwing in something really wacky just to make it fun - like wasabi peas or candied ginger - but didn't think it would be fair.
So I am going to go with these four ingredients: black beans, Great Northern beans, a bag of torn up red leaf lettuce, and three avocados. This is a genuine cupboard challenge; I need to use up the avocados before they get too soft, and while I could just throw them in a guacamole, I thought I'd include them and see what happens. Bonus points if you come up with something other than two-bean tacos!
