Grapefruit and Avocado Salad

Kind of different, but very mild and good. Makes 6 appetizer of side salads

1 grapefruit, peeled
1/2 white onion, halved and thinly sliced
2 ripe avocados, halved, peeled, and cut into thin slices
1 7-oz. bag Riviera Blend salad (in the refrigerated part of the produce section)
3 Tbsp. extra-virgin olive oil
Kosher salt and freshly ground pepper

Over a large salad bowl, separate the grapefruit slices, catching the juice in the bowl. Remove the seeds (I peeled off the skin from each slice to make it easier to eat). Add the grapefruit slices to the bowl. Add the onion, avocados, salad mix, and olive oil and gently toss. Season with salt and pepper to taste.
