how do you get the same amount of vitamins that meats provide?

because meats are a convenient source of some vitamins, it just takes a little more planning on my part to make sure that i consume enough grains (for iron), leafy green vegetables (for calcium), and protein foods. to get protein (the big question most people ask), i eat a lot of beans (green beans, chickpeas, kidney beans, hummus, chili, to name a few), lentils, and nuts and seeds (tahini/sesame seed spread, almond butter, ground flax seeds), and i drink soymilk. i also drink vanilla rice milk, which doesn't provide much protein, but contains loads of calcium, vitamin D, B12, and other essential vitamins. i try to eat a variety of different grains and vegetables, because this is what provides my body with all the essential amino acids it needs for protein. in general, vegetarian diets are high in most vitamins as long as you like your fruits and vegetables and are willing to eat a wide variety of foods!
