shopping budget/meal planning

So this week is our first week of gluten free and ive managed to get a rough estimate for our shopping ($209)I think it may blow out to closer to 250 but alot of the food is freezer friendly.
This week I plan to make:
4 loaves of rice bread
1 loaf of gluten free fruit bread
35 gluten free muesli cookies
24 mini tuna,corn,sweet potato frittatas
Also doing a big batch of Gluten free chicken nuggets.
