Cheap, Filling Menu

Yesterday and today I worked on writing down my ideas for a cheap menu that still offers the calories we need. I haven't actually priced this out at the store, but it should come in pretty low. The menu comes to just over 1800 calories (1862 w/my calculations), but will be more or less depending on the type of bread etc. that we buy or make each time. This menu doesn't really include dinner or much fresh produce. I was focused on cheap, filling calories and I'm hoping we'll get our garden planted this next week so we can add our own fresh vegetables. Adding a roast chicken, soup, or hot dogs to the baked fries for dinner will add more variety and calories without costing an arm and a leg and frozen vegetables are a good addition as well. So without further ado, the menu (listed as amt. per person)

Breakfast:
1 c. milk
2 biscuits (made from Krusteaz pancake mix: 1 c mix combined with 1/3 c water should make
                    about 8-9 biscuits)
1 tbsp gravy mix (I calculated the calories by 1 tbsp dry mix, may be more if mixed w/milk)
1 shredded potato cooked in 1 tbsp butter

Snack/Brunch:
pb and jelly sandwich (2 slices bread, 2 tbsp pb and 2 tbsp jelly)

Lunch:
1 c. rice
1/4 c. canned beans (we prefer black beans)

Snacks:
Homemade apple pie (1/12th of the pie)--this little slice makes up a whopping 286 calories so if you don't want to or can't make it, substitute something high calorie like maybe two pop-tarts or some spaghetti)
1 c. milk

Baked fries (1 potato cut in long strips, covered in 1 tbsp oil, sprinkled with salt and baked)
