Vegan here. Haven't ever had a problem with energy, lots of fresh, organic veggies, grains and legumes. I try and avoid processed items, using tofu maybe twice a week. Tonight I'm having a broccoli chickpea casserole, and a big side of kale.
Also check out your local library, there are lots of good books out there now that can help simplify your diet for you. I recently just found "Vegetarian Sports Nutrition", seems pretty elementary so far, but I'm only about 20 pages in.
Shoot me a message or post away if you want any good recipes etc.
peace
