How can I eat healthier with a busy college/work schedule?

I’m 5’5” and around 140 lbs. I’d like to get down to 130ish and I just want to be healthier and change my way of eating. My self confidence has plummeted recently.

However, I have a busy schedule. I work 10–5 or 6 and go to school from 6–9. Add in studying and finding time to sleep or relax, and there isn’t much time for working out. I’m going to try to be more active, but I need to focus on my food habits more for now.

Here’s what I have planned as far as meal options go:

Breakfast

Hot Oatmeal with fruit or berries
Cereal with skim milk and fruit
Grain toast with almond butter and fruit

Lunch

Grain wrap with low fat meats/cheese and vegetable
Leftovers from dinner

Dinner

Stir fry
Spaghetti

Snacks

Veggies (carrots, green beans, corn)
Fruits (strawberries, bananas, grapes, watermelon)
Nuts (almonds, pistachios)
Yogurt

So, how does this look? I’m going to aim for 1300–1500 calories a day, but I’m more focused on making healthier choices than counting calories.

My BIGGEST question is this: Those dinner options may work for Friday through Sunday, but what about during the week? I have about 30 minutes to leave work and get to class. What kinds of foods can I eat on the way or in my car that won’t ruin my diet? I can’t think of anything!

Any help/insight would be greatly appreciated. :)
