<p>I think Morningstar makes the best veggie burgers, and they have a ton of varieties. Also, if you live near a Trader Joes or Whole Foods, the amount of meat alternatives there are astounding- ‘chicken’ nuggets, 'meat’balls, taco ‘meat,’ etc etc- all meatless. Amys is a great line of vegetarian frozen food.
Have him google some vegetarian recipes that sound interesting to him for ideas. </p>
<p>Will he eat dairy and eggs? Great sources of protein- Omelettes, quiches, yogurt. If you’re really concerned about protein, protein powder is widely available at healthfood stores.</p>
