Just a word of caution: Try not to overcook the broccoli, cauliflower and other vegetables. Overcooking degrades the nutrients and the fiber. In my opinion, you can take healthy vegetables and destroy them by cooking the life out of them. Also, if you're using white rice, try whole grain instead.
How much rice does the recipe call for for a single serving? Too much rice may give you too many calories.
How much cauliflower? How much chickpeas? You need enough chickpeas to get your protein requirement.
What kind of fat does the recipe call for? Olive oil? If so, don't cook the olive oil.
How much will you eat? Will you be making single servings?
As you can see, there are lots of things to think about. One or two healthy ingredients doesn't necessarily make the healthiest meal. It's everything about how the meal is put together.
If you eat a good diet with lots of vegetables, whole grains, legumes and fruit etc., and eliminate processed foods, you won't have to worry about "colon buildup". Mother-nature will take care of everything.
