A Sicillian Orange Salad

This salad is typically made with romaine lettuce, and could be called a vegetarian orange ceasar.
It is extremely simple to make and can be put together in a few minutes, with a very high "Oooh" factor from your guests or spouse!
SO, lets first have a look at the ingredients list:
For four people:
Two nice heads of romaine lettuce,
2 medium sized oranges,  peeled,
A bulb of fennel (Florence fennel, sometimes mislabeled anise in the supermarket, but actually a completely different plant!),
A large sweet red onion, or a Vidalia,
2 cups arugula,
1/2 cup Walnuts, (optional),
4 or 5  mushrooms (optional).

Dressing
1/3 cup vegenase (you can use mayo, but I choose to be completely vegan and the result is lighter),
1/2 cup orange juice,
1/4 cup Extra Virgin olive oil,
4 tablespoons balsamic vinegar,
pepper,
salt.

For this example we will  just make a salad for two, so the ingredients are halved.
1 Slice the fennel thinly (fennel can be tough, so this is important),
2 Cut the onion in half, and slice,
3 Chop the arugula coarsely,
4 Peel, remove the pith, and slice the orange thinly (not too thin, or it falls apart),
5 Slice the mushrooms
6 Chop the walnuts coarsely
7 Chop the lettuce,
8 mix it all together
Now make the dressing...

The acidity or sweetness of a dressing is always a personal preference, so you can adjust this to taste.
The outline is 3 measures  orange juice, 2 measures vegenase or mayo, 1 measure olive oil, 1/2 measure balsamic vinegar.

For our salad for two that breaks down to:
1 cup orange juice,
add
2/3 cup vegenase (or mayo)
Stir well with a fork
It may be better to add the OJ to the mayo rather than the other way around.
Slowly add 1/3 cup of extra virgin olive oil while stirring
Finish up with 2 tablespoons of balsamic vinegar.
Add pepper to taste and stir well.
Add to your salad and toss...

When you have mixed all the ingredients, proudly serve your creation and feed the masses!
