Cruditiès

There are always many things available in the markets that can be used for this:

asparagus (very young only)
broccoli
carrots
cauliflower
celery
cherry tomatoes
mushrooms
peppers: yellow, red, green
radishes
scallions
squashes: zucchini, pale green, yellow
sugar snap peas (not paleo, for guests)

Most (all?) of these can be smoked in a Camerons Stovetop smoker for about 8 to 18 minutes (depending on how full).
