I think that's a great idea Jessica! I always use my blender to juice our fruit and veggies, especially for breakfast.
I wrote a great breakfast recipe which is great for vegans or anyone who wants a great nutriet/antioxidant intake:
Breakfast Shake Recipe for Vegans...or Anyone - Discuss Cooking - Cooking Forums
Enjoy! Of course this recipe can be entirely tweaked towards your preference.
Juicing veg is great for a bunch of reasons BUT you do lose the fiber content.
When i had severe colitis it was my go-to to make sure i was getting high quality micronutrients.
But way better to make a salad!
If you are looking to replace a meal, maybe add some melted coconut oil to it. Fat often helps w nutrient transport.
Also, try to drink it as soon as it is juiced or store briefly in a container where there is little air space. Once nutrients are exposed to air they begin losing their nutritional content.
If you want an all around flexible machine that will juice most fruits and vegetables, I'd get a masticating juicer. Though they can be a little expensive. You can also look a centrifugal juicers, which are cheaper, but don't juice leafy vegetables or wheat grass well.
