use tomato juice for more liquid in your soup if you cook with rice
try different flavors of diced tomatoes like fire roasted, Italian style, or chili ready tomatoes
works great with brown rice and chicken broth too
add Italian seasoning instead of just thyme if you like that
use a pressure cooker to keep this a one pot meal
leave out rice to keep it low carb or keto
add cheese to make it richer
add more or less rice to make it thicker or thinner
serve it with a hunk of crusty bread
add black beans and corn for a southwest twist
