My DD (10) likes Boost High Protein drinks. It has 15g of protein per 8oz serving (8oz milk has 8g). She used to drink one 3 days per week when we pulled her from school early for practice... She's quite a slow eater and she'd have just 5 minutes to ingest nutrition to sustain a 4 hour practice. So she'd drink that and eat approx. 5 grapes. 
She'll occasionally eat protein bars but not very often. Sometimes I'll buy some and chop them into small squares and just add a couple to her gym bag with her snack (nuts, pretzels, and a fruit). DS loves them, too - he wants to be like big sis. We restrict them to his practice days (he'd eat them every day, pretty sure), so twice per week, but I usually cut them in half (he's 7). Sometimes he's sneaky, though.
We'll usually buy Balance bars - both kids are partial to cookie dough flavor, though sometimes they'll do chocolate mint Luna bars, too.
Doc says it's all ok, but he'd much prefer they eat actual food.
