My favorite side dish with meat is a salad.
I like to get some lettuce grown locally in one of those high tunnels. It's usually a mix of baby romaine, spinach, and some bib lettuces. Then I add some frozen green beans or peas. Yep. Frozen. I thaw them first, but they have already been blanched before freezing and are crunchy and bright green. I will then add some sprouts, cut up a raw turnip into julienne strips and then top it off with some mixed crispy nuts and a mix of cold expressed olive oil and kombucha or a nice red wine vinegar. Salt, pepper and dive in.
My second favorite side dish is turnip greens cooked at a low temperature with a little bacon, onion and a diced turnip.
Third favorite is collard greens with the stems removed and again cooked slowly with a little bacon fat, vinegar and salt and pepper.
Finally, I love to go out and walk the edges of the farm fields and pick something known locally as "cresses". I believe these are wild mustard greens. Picked young, they cook up tender and make wonderful additions to any soup or stew.
