The recommended intake of both fruits & vegetables per day is 3.5 cups. That is 3.5 cups of all of them combined. If you think about it that really isn't a lot. 1/2 to 1 cup from each colour provides your whole daily needs and then some.
One way to keep the cost low and the nutrition high is to use fruits & vegetables for smoothies. A half-cup of frozen fruit & a half cup of milk (or substitute) will make a thick smoothie that can be eaten like a pudding. Add more liquid and it becomes thinner and it also changes from 1 serving to two.
You can use fresh fruit & vegetables to make your own smoothie mixes that can be frozen for a quick snack later. You can find a few ideas here. Plus below are some other ideas on how to add more colour to your diet.
