Healthy lunch ideas around 400 cals

Lasagna roll up - there was a recipe on the mfp blog recently, you can make them in advance and freeze them - made with low fat ricotta and cheddar served with a side salad.

Depending on how you make these, they're closer to 300 kcal, so you can add in a treat (apple, fruit salad, homemade muffin):

• Tuna salad made w/light mayo served on rice crackers, with steamed veg or side salad. (I do this on days where I know I'm going to have a snack or early dinner since I only use about half a can of tuna.)
  
• Chicken served on a large salad w/ lots of veg: onion, celery, broccoli, etc. and some tomatoes, (I usually bake a bunch of chicken for the week usually with various herb mixes for flavour, and then heat it back up for lunch or dinner).
  
• Chicken, beef or tofu stir fry served over brown rice (something like basmati with higher protein) bit of oyster sauce, rice vinegar (or white wine vinegar), low salt soy sauce and garlic/ginger for the marinade.

2 Bean & cheese Tostadas
-2 corn tostadas
-1/2 cup refried beans
-1/4 cup of shredded cheese

broil in the oven or throw it in the microwave for about 30 seconds until beans are warm and cheese is melted. Then top each tostada with 1 tablespoon of sour cream. I also top mine with jalapenos, onions and taco bell taco sauce.

I had this for lunch yesterday and it was about 380 calories. Hubby and I practically lived on these when we were in college. So cheap and easy. 18 years later we still eat them.

Burrito bowls - Depending on the amount of chicken it is anywhere between 340-380 and ground sirloin for 4oz is 417.
