Everything can be enhanced. I wouldn't dilute my beefy flavor with mustard personally.
there is no tight or wrong, obvs, but I find that the sourness of the mustard and pickles balances the sweetness of the fatty beef. I don't have a sweet tooth so I gravitate towards a dash bitter or sour items. I tend to enjoy things like arugula, rapini and amaro more than most.
