In a self-sealing plastic bag combine cubed pork, soy sauce, vinegar, ginger and Dijon-style mustard (or Chinese Five Spice); seal bag and refrigerate for 1 to 4 hours.
Prepare medium-hot fire with charcoal or preheat gas to medium high.
Remove pork from marinade, reserving marinade. Thread pork, sweet peppers, mushrooms, and zucchini alternately onto 8 skewers. Brush or drizzle with reserved marinade. Grill kabobs directly over fire, turning to brown evenly, for 5 minutes. Brush kabobs with the melted jelly. Continue to grill for 3 to 10 minutes more or until tender. Let rest 3 minutes before serving.
4 servings (2 kabobs each)
*Kabob ingredients don’t need to be limited to the vegetables listed. There are several ways to customize kabobs; try incorporating cherry tomatoes, broccoli (precooked until crisp-tender), pineapple chunks (fresh or canned), yellow summer squash, red onion wedges, baby carrots (precooked until crisp-tender), halved tiny new potatoes (precooked until tender) or try adding fresh sprigs of herbs.
Leave a little space between each ingredient when threading them onto the skewers. This assures even cooking.
