I've tried pretty much every vegan protein powder out there, and my top favorites are Garden of Life Greens & Protein and Orgain Organic Protein-- both in chocolate. I've tried Aloha recently and was not thrilled with the flavor or texture at all, so I'd skip that brand. Vega is okay but is more expensive than the rest and is not organic, so I just crossed it out on my list.
If you need to add more protein and require a vegetarian option, I'd just suggest quinoa, beans, legumes, eggs, and nuts. I've been a vegetarian for more than half of my life, and those have always been my go-to's. But if having issues eating in general is hard, just do a double serving of protein powder a day (in a green smoothie for extra calories/nutrition) to meet those goals.
I like Garden of Life’s Raw Protein and Greens. Drank it during my pregnancy as well: https://www.amazon.com/dp/B01A9IFE8K/ref=cm_sw_r_cp_api_glt_fabc_PWBX70M7GQDV6VVX4RD2?_encoding=UTF8&psc=1
I like the Protein & Greens from Garden Of Life 20g protein and 0g net carbs. Comes out to about $1 per serving
