It can be tough, but my go to meal when I need a high calorie clean meal is definitely the following.
12 oz chicken breast
-depends on what brand of chicken breast but they typically range from 100-150 calories per 4 oz so there is about 300-450 calories total here with about 60 or so grams of protein right here
Mission Wheat Tortilla
-these are the ones that are high fiber, as in 31 grams of carbs total but 21 of those grams are fiber, 4.5 grams of fat, and 8 grams of protein equaling 200 calories.
1 cup kraft fat free cheddar cheese
-surprised I don't hear more people talking about cheese as a great source of getting extra protein. Usually 9 grams per 1/4 cup and only 45 calories here depending on the brand. Lookin at 36 grams total protein here alone per cup. No carbs(back of package says less than 1g), no fat, just protein.
-calorie free condiment for the taste factor
So my typical taco/burrito/quesdilla/whatever the hell you call has the following totals (the cheese will vary depending on what I need for that meal at that time of day so the example below is the one when I need a ton of protein)
830 calories, 110 grams protein, 31 grams of carbs, 21 grams of fiber, 4.5 grams of fat
Just an idea to keep in mind if you are struggling to meet certain numbers, and it tastes pretty good too. The fat free cheese can be expensive though, but Wal-mart has big bags of their brand of cheese for 7 bucks(good deal) just watch the fat content with the wal-mart cheese.
