I think the kids will really like this salad!  The colors are gorgeous, especially if you use spinach.

1/4 cup balsamic vinegar
1-1/2 tablespoons Dijon mustard
1 tablespoon honey
1 small shallot, chopped
2 smallish cloves of garlic, peeled
1/2 teaspoon salt
1/2 teaspoon black pepper
1/2 cup olive oil
1 head lettuce, spinach or both, dried and torn
1/2 red onion, sliced thinly
1/4 cup sliced almonds, lightly toasted
1 pint fresh strawberries sliced
1/2 cup crumbled feta cheese (optional)

To make the dressing place the balsamic vinegar, Dijon mustard, honey, shallot, garlic, salt and pepper into a bowl, cruet or food processor.  Blend all of the ingredients together.  Slowly poor in the olive oil while blending until emulsified.  Set aside while you make the salad.

Get out a nice salad bowl and add your lettuce, spinach or your mix of both to it.  Top that with the red onion, almonds, strawberries and feta cheese and toss gently with the dressing.  This dressing is also great on any number of other salads, so refrigerate and keep any leftover dressing.
