Romaine and Watercress Salad with Fennel, Oranges and Tuna

Although this 5 minute salad is perfect just as it is, it is also wonderful with slivers of leftover grilled chicken or steak mixed in.

1 head Romaine lettuce, inner leaves only, torn
1 bunch arugula, washed well and torn
1 bunch watercress, torn
1 small head radicchio, torn
1 ripe avocado, cubed
1 ripe papaya, peeled, seeded and cubed
12 cherry tomatoes, halved
¼ cup crumbled feta cheese
4 teaspoons extra virgin olive oil
4 teaspoons fresh lemon juice
½ teaspoon kosher salt
¼- ½ teaspoon black pepper

Place the Romaine, arugula, watercress and radicchio in a large serving bowl and toss to combine. Add the avocado, papaya, tomatoes and feta cheese and gently toss. Drizzle with the oil, lemon juice, salt and pepper.
