Wash and cook brown rice according to package instruction.

Prepare your bell peppers, onion, and garlic: wash, slice, chop and place them all on a big bowl. [You also have to option to quick fry your onion and garlic if you like, before mixing them with other ingredients]

On the same bowl, add in all the specified protein and spices [and the optional ingredients you fancy]. Set aside and cover while waiting for rice to cook.

Wash your lettuce, then dry, and cut them into bite sizes by hands. Transfer 1 serving of lettuce on a serving bowl and set aside. Keep leftover lettuce on a ziplock bag and store in fridge. Note: Using a knife to cut lettuce makes lettuce taste bitter. Strange but true, based from experience.

Soon as the brown rice is cooked. Take 1 cup rice. Add them to the bowl of quickly marinated veggies (w/o lettuce). Mix them well.

For 1 serve, transfer 1/2 cup brown rice mixture on the serving bowl with lettuce and stir them a bit. Garnish with extra chopped walnuts or dried fruit if you want.

Keep the brown rice mix leftovers on a container then store in fridge. And it would taste even better the next day! If the leftover mixture has cooled down, you can mix-in the lettuce before storing the meal in fridge. Or alternatively, just bring a ziplock of lettuce with your packed brown rice and mix them upon consumption. Enjoy!
