Every ingredient is a staple at Charlotte grocers—black beans, tomatoes, red onion, avocado, parsley, lemon, and avocado oil are all routinely stocked at Harris Teeter, Kroger, and Walmart. Cost per serving runs under $2, driven mainly by the avocado; the rest are low-margin staples. The stated 10 minutes is honest for mixing—no cooking required—though chopping the avocado and red onion adds 3–4 minutes in practice, bringing real time to 13–14 minutes. This is a straightforward no-cook side that works for weeknight dinner prep and reheats adequately for lunch the next day, though the avocado will oxidize slightly if left overnight. A solid, accessible dish without drawbacks, but not extraordinary enough to warrant a higher score.
