Rinse and spin-dry the greens and tip into a large salad bowl. Add the mint leaves, radicchio and red onion, toss to combine.
Distribute the cantaloupe, blue cheese and walnut halves on top of the greens. Drizzle the dressing on the salad and toss to combine. Serve immediately.
Notes
Choose a variety of leafy salad greens such as butter lettuce, oak leaf, frisée, baby spinach or arugula.
Pass on the pre-crumbled blue cheese and buy a chunk and crumble it yourself.
Tear the salad greens directly into the basket of the salad spinner, then set the basket into a pan of ice water, rinse, drain and then spin them dry.
This salad an be made a couple hours in advance without the dressing added. Cover the salad with a damp towel and refrigerate until ready to toss with the dressing and serve.
