Are her protein and lysine requirements being met by her diet?  How much additional protein do you want to supplement?

I checked a nutritional data site and 1 cup of frozen unprepared) peas has 7 grams of protein and one cup of dried split peas has 48 grams of protein.  

Two other sources of protein that are often recommended are whey protein isolate 90% (30 grams = 27 grams of protein) and Pea Powder.  I forgot to write down the protein available in pea powder, but you can find it on the Pure Bulk site. Coincidentally, the whey protein isolate and pea powder are on sale right now.
