Instructions
Prepare the Radicchio
Start by preparing the radicchio in order to remove most of its bitterness. Cut the head of radicchio in quarters vertically. Make a diagonal cut to remove the core from each quarter. Chop the radicchio in 1-inch pieces.
Prepare a large bowl of ice cold water. Submerge the chopped radicchio in the water. Let it soak for (a minimum of) 30 minutes, up to 2 hours. The longer in the water, the more bitterness is broken down.
Prepare the Citrus Segments
Prepare the orange segments with a sharp knife. Cut off the top and the bottom of the orange, just enough to expose the segments.
Hold the orange upward and run the knife downwards. Remove the skin and the pulp, removing the least of the orange segment as possible.
Place a bowl on your worksurface to catch the falling juice. Hold the orange other the bowl. Run the knife as close to the section walls as possible, cutting all the way to the center, releasing the segments.
Repeat the same process with the grapefruit, also making sure to catch its juices. Reserve the citrus juices for the salad dressing.
Assemble the Salad
Prepare the dressing by combining the reserved citrus juices, olive oil, Dijon mustard, sugar, salt, and pepper. Whisk together until combined.
Remove the chopped radicchio from the ice water and place on a clean dish towel. Pat them down to make sure they are nice and dry.
Combine the dry pieces of radicchio and the arugula in a large bowl. Drizzle with your desired amount of dressing and toss.
At this point you can either, toss in the Feta and Citrus Segments with the greens, or serve them on the side. Sprinkle with the Fried Onion and enjoy!
