Make Your own King Trumpet Scallop Skewers:

In Japan, the most popular way to serve king trumpet scallops is just to slit them in half down the middle and liberally brush them with yakitori sauce while grilling. Of course, this wouldn’t be Texas Real Food if we didn’t add a Texan twist to the recipe. We’ll be adding bacon strips in between the mushroom “scallops” to kick the flavor up a notch. The bacon will crisp up while grilling and the mushrooms will absorb the oils being released by the bacon, infusing it with a lovely bacon flavor.
