Trim both the root and tip ends off of the radishes and halve them lengthwise. (If any radishes are larger, quarter them to keep all the pieces at a similar size so that they cook evenly.) Add the butter and 1/2 teaspoon salt to a 2-quart baking dish. Microwave on high until the butter is melted, 30 seconds to 1 minute.
Remove the dish from the microwave and add the radishes, gently tossing to coat. Cover tightly with plastic wrap and use a sharp paring knife to poke 6 small holes in the top. Microwave on high for 5 minutes. Carefully uncover and give the radishes a stir. Cover again and microwave on high until the radishes are tender, about 5 additional minutes. Carefully uncover and stir the chives and honey into the radishes. Scoop the radishes into a serving bowl and pour any remaining butter over the top. Sprinkle with the pepitas and serve immediately.
