Ingredients

For the Salad:

2 cups cauliflower florets
2 cups cherry or grape tomatoes (about 10 oz)
2 cups chopped carrots (about 4 medium)
1 cucumber, seeded and chopped
1 bell pepper (any color), seeded and chopped

For the Vinaigrette:

1/2 cup extra virgin olive oil
1/2 cup red wine vinegar
2 Tablespoons minced shallots
4 teaspoons Dijon mustard
2 teaspoons Italian seasoning
2 cloves garlic, pressed or minced
Salt and black pepper, to taste

Directions

Prepare the vinaigrette:
In a jar with a tight-fitting lid or a mixing bowl, combine the olive oil, red wine vinegar, shallots, Dijon mustard, Italian seasoning, and garlic. Shake or whisk until well blended. Taste and adjust the seasoning with salt, pepper, or a little more oil if you prefer a milder flavor.
Marinate the vegetables:
Place the cauliflower, tomatoes, carrots, cucumber, and bell pepper in a large mixing bowl. Pour in about 3/4 of the vinaigrette and toss until all the vegetables are evenly coated.
Chill and serve:
Cover and refrigerate for at least 4 hours, or up to overnight, to allow the flavors to meld. Before serving, toss with the remaining vinaigrette and adjust seasoning with additional salt and pepper if needed.
