Spinach, Apple, & Cheese Panini Sandwich

This is one of my favorite Eat Clean recipes!  I’m not a huge meat eater, so the fact that this has no meat is a plus for me.  The flavors together are so amazing!  I’ve eaten this sandwich five times in the past week (yes, it’s that good).  It’s quick and easy to put together.  I highly recommend it! YUMMY!

SPINACH, APPLE & CHEESE PANINI SANDWICH WITH CARAMELIZED ONIONS

Serves 4

1 tsp extra-virgin olive oil
1 cup sliced yellow onion (or about 1/2 large onion)
1 large ambrosia apple, thinly sliced and tossed with juice of 1 lime
1 cup spinach leaves, stems removed
4oz low-fat Swiss cheese, thinly sliced into 4 slices
8 slices whole-wheat sourdough bread or 4 ciabatta rolls

Heat a medium saucepan over medium-high heat for 1 to 2 minutes. Add oil and onions. Stir occasionally. After about 5 minutes, onions will start to caramelize, and you will need to stir constantly for about 5 more minutes. Onions should be evenly browned, not burnt. Remove from heat and set aside.

To assemble sandwiches, spread about 2 tbsp of onions on each of 4 pieces of bread. Top each slice with about 4 spinach leaves, 1 slice of cheese and 3 pieces of apple. Top with other slices of bread.

Heat grill. After assembling sandwiches, grill for about 2.5 minutes, then flip and grill for another 2.5 minutes. Serve with extra apple slices.
