quick pickle stacked sandwich

mastering the art of pickling has been on my bucket list for nearly two years now. but, i'm not the most patient person in the world, so i've settled for quick pickle recipes as kinda, sorta checking this skill off my list. also, until i move out of my one bedroom apartment, i have a feeling space will continue to hold me back from shelves and shelves of pickled and preserved foods...le sigh. 

so, what is quick pickling? it's a super simple shortcut to getting the tang, brine and crunch we love in pickled foods, but doing it in just a few hours. starting to quick pickle is a slippery slope, though, so don't say i didn't warn you. once i learned how to do red onions (thanks, bon appetit!), next it was multicolored carrots...then it was cauliflower...then it was radishes. i couldn't look at crunchy vegetable without instantly becoming a portlandia episode of "we can pickle that!" irl.

all you need on hand is the vegetable of your choice (in this case, radishes), a vinegar, such as white or apple cider vinegar, your preferred spices/herbs and white sugar. for my herb/spice mix, i really like ball's mixed pickling spice, which will only set you back about $4 and makes this process even quicker. i really like ginger for pickled carrots, for example, but use no spices/herbs at all for pickled red onion. the complexity and flavor is totally up to you, and thekitchn has a great guide to some flavor combinations. 

recipes range from calling for a few days until quick pickles are ready to just 20 minutes. for this sandwich, i let the radishes sit for about 5 hours, but i think ideally you should wait at least 24 hours to really let the vinegar do its magic. you'll be rewarded with a hot pink bounty of veggies.

to complement the peppery radishes, i've layered cumin- and garlic-roasted sweet potato rounds, smooth hummus, coarse dijon mustard and fresh spinach. if you have extra hummus on hand, you can use it as a dip for the pickled radishes, as well as the sweet potato rounds if you crisp them up a bit longer in the oven.

all in all, this sandwich is bursting with flavor and color, and makes for a wonderful lunchtime toast. it's also a testament to DIY cooking, as nearly every single element of this sandwich was homemade - from the bread to the picked radishes, and everything in between. short of growing the spinach and making the mustard yourself, there's a lot of homemade pride packed into each layer.
