Begin by preparing your cauliflower rice.
Use 1 large head of cauliflower and chop into florets. Pulse for about 10-15 seconds in a food processor - do not over process.
Heat large skillet and 1 Tbsp oil - add cauliflower rice, saute for 5 minutes - remove from the heat, then spread cauliflower "rice" on a rimmed baking sheet, and let cool.
Place rice in a large bowl. Add all vegetables and fresh herbs, and mix well.
Whisk together lemon juice, oil, salt and pepper.
Pour dressing over vegetable mixture and stir to coat.
Add more salt and lemon pepper to taste. Serve immediately or refrigerate to let flavors combine for a few hours.
