Among the important things that I always try to keep them in my daily diet is vegetable and fruit, specially california vegetable mix, corn, green peas, apple, banana, orange and mandarin. What I usually do is, I buy a few packs of frozen vegetables, defrost them by boiling them in hot water, then keeping them in fridge in small quantities and serve them in a daily basis.
For the fruit, I buy apple, banana, Orange and mandarin, peel the skin off fruit, dice and mix them, keep them in fridge in small bags and serve them in a daily basis. I usually add salt, chili powder and pepper to the vegetable, boil it in a little bit of water and serve it like a soup.
About the calories, each bag of california vegetable in the below photo contains about 100 calories and each bag of corn and green peas in the below photo contains about 300 calories.
