Menus and Grocery Budget - Last Week

I haven't quite finished out budget for this year as there are so many changes in our life right now. For groceries though, I think the budget will be approximately $100 per week, plus $200 for Costco. We currently spend too much money going out, and I'd like to limit that to $200 per month. While that may sound like way too much for two people, it would be a vast improvement over our current spending.

Here's the menu we followed (mostly) for last week:

Sunday: Pizza (whole wheat dough from Trader Joe's with salami and olives)
Monday: Slow cooker beans and sausage
Tuesday: Steaks (hubby found steaks on sale and convinced me the baby wanted steak - didn't take much convincing. I just move the rest of the menu on day forward)
Wednesday: Cod, potatoes, green beans
Thursday: Pasta Puttanesca (froze half for later)
Friday: Sushi and for me, alas, cooked Japanese food - we ate out and spent
Saturday: Tapas (Garlic shrimp, Spanish ham and cheese, Fierce Potatoes, Spinach, olives)
Sunday: Thai Pork in the slow cooker.

Spending so far for January:

Groceries:
Trader Joes - $94.06
Safeway: $132.35
Remaining for this month: $173.91
(Obviously seriously not good)

Eating Out:
Japanese Food: $77
Remaining for this month: $123
We can manage through this one easily...
