We enjoy the Voila! Three Cheese Chicken from Birds Eye $6.49 But we add our own additional frozen vegetables (plain, 1 pound, Italian blend) and cubed boneless skinless chicken (marinated for a day, then cooked and cubed) to make it come out to about $2.25 per serving (4) and about 300 Calories.
For $2.50 in the added ingredients, double the yield and improves the carbs, sodium, and protein. The calories are virtually identical.
The 21 ounce Birds-Eye package says that it serves three, but in practice we find that it serves two. Add your own generic frozen veggies and cubed cooked chicken and you serve four.
Frankly, it's awesome how this "stretching" just makes the whole thing both more efficient and better nutritionally (e.g. not having a crazy level of sodium). Kinda says something about what the original meal is like...
