Brown beef in large heavy-bottom skillet over medium heat, mixing in oregano, sea salt, and mushrooms as it cooks. Cook until fully browned.
Remove from skillet with slotted spoon, reserving fat. Place in a clean bowl and set aside.
Add cauliflower and onion to skillet. Saute for 5 minutes, stirring only every 2 minutes to prevent sticking, until lightly browned and tender. Remove from heat.
Combine olive oil and vinegar in a jar, tightly secure lid, and shake to combine.
Fill bowls with cauli rice, top with beef, basil, and drizzle oil and vinegar dressing over
