New Weekday Eating Plan

So, for the first five months of my journey, I've been doing a lot of the same eating at work (with too many interruptions): oatmeal, yogurt, and an Eating Right frozen meal. But I'm cheap. And Safeway stopped having them on sale. They used to be $2 each, but now they're $3 each. That's how cheap I am--I'm not willing to pay more for my meals (at work). :) So, I have a new menu:

7 am: whole wheat English muffin with Super Duper Walnut Butter ~$1.00; 210 Calories
10 am: 2/3 cup fat free plain yogurt with sprinkling of crystal light and 5 drops of stetvia concentrate ~ $0.50; 81 Calories
1 pm: 1/2 cup quick oats, 1 tbsp cheese, 3 oz taco turkey ~$1.00; 295 Calories
3 pm: banana $0.25; 100 Calories

Total Cost for work food: $2.75.
Total Calories for work food: about 686
Not bad!  I think.  Is that enough food?  Or should I eat more??

Okay, on to my totals so far:
