I estimated 38 servings from your post:
chili (6x2) 12
turkey burgers 6
lasagne (4x2) 8
Soup (5x2) 10
38 servings (plus side dishes) for $90 is $2.36 a serving.
At 42 meals a week (21x2) this would be $99.
However, these are primarily lunch/supper/dinner items and I'm sure breakfasts can be done for less. Sounds good.
