Skewers
Combine oil, lemon juice, rosemary, parsley, garlic, and salt in a large resealable bag.
Add pork; marinate, refrigerated, for 30 minutes (to 4 hours).
Preheat grill or broiler on high.
Boil water in steamer or large saucepan over high heat. Reduce heat to medium-high. Place sweet potato pieces in steamer basket; cook for 3 to 4 minutes, or until tender-crisp. Place in ice water bath to stop cooking process. Set aside.
Place a piece of chicken, sweet potato, onion, red bell pepper, and green bell pepper onto a skewer. Repeat, so the skewer has two pieces of each ingredient. Repeat with five remaining skewers. Discard marinade that contained chicken.
Grill (or broil) skewers for 8 to 10 minutes, turning every 2 minutes, or until sweet potato is softened and pork is no longer pink in the middle.
Salad
Combine water and ½ tsp. salt in a medium bowl; mix to dissolve salt.
Submerge apple slices in water. Let sit for 5 minutes; drain water. Set aside.
While apple is sitting, combine vinegar, oil, remaining ¼ tsp. salt, and honey in a small bowl; whisk to blend. Evenly divide dressing between 4 one-quart Mason jars. Set aside.
Evenly layer apples, fennel, pecans, salad greens, and arugula on top of dressing in jars.
Serve immediately or cover and refrigerate for up to 3 days. Shake before serving.
