Preheat oven to 400 F.
Spray a baking sheet with cooking spray or cover with a sheet of parchment paper. Place Delicata squash rings on the tray.
Brush the tops of the squash ring with half of the brown butter and sprinkle with half of the brown sugar.
Roast for approximately 10 minutes and flip rings over.
Brush the top side with the remaining butter and sprinkle with the rest of the brown sugar.
Continue to bake for another 5 minutes or so, until a knife inserts easily into the flesh of the squash. Remove from the oven and cool.
To make salad, place arugula in the bowl, and arrange roasted Delicata squash rings on top along with dried cranberries, toasted pecans, and blue cheese.
Toss with all with olive oil first and then vinegar and lemon juice. Season to taste with lemon pepper, salt, and pepper.
