For lunch, pack him a turkey sandwich with cheese and an apple with pb. Snack is hummus or apple and pb or berries and a cheese wedge. Dinner -- chicken or chili or meatballs with a salad and some pasta or rice.
Whenever you can get him to add a 4th meal, give him a mix of protein and carbs. Leftovers are great. My swimmer was a huge fan of second breakfast, which was usually a ridiculous number of eggs and an apple (or pancakes if it was the weekend). Peanut butter sandwiches were very portable. Same with hard boiled eggs.
If the sports are cardio intensive, like swimming or running or higher level soccer, you will want to up the carbs before practice for energy.
Good tips. For at home(bc there are a lot of kids on teams or at school with allergies), trail mix is another good high calorie snack.
