Bring 2 cups of water to a boil. Add peas, reduce heat to a slow boil for approximately 25 minutes, until barely tender, drain and cool (1/2 cup split peas will basically double in size after cooking).
In a large bowl, mix together cauliflower, broccoli, onion, cheese, crumbled bacon and tomatoes. Add cooled peas.
Mix dressing together in a medium size bowl and check for taste before putting it on the salad. Add more lemon juice if you want the dressing to challenge your taste buds a little.
Cover and refrigerate prior to serving, anywhere from 3 – 24 hours for the best flavor.
