fiber is our friend
there are lots of things you can add to get more fiber
la tortilla factory makes these wonderful low carb tortilla/wraps - in all sorts of flavors and whole grains - the minimum amount of fiber in most of hem is 8 grams.
Vegetables also add in fiber to your diet - and not boring iceberg lettuce - roasted broccoli with just a bit of olive oil and garlic will give yu a big fiber bang.
What's the layout she's given youo?
a certain percentage protein/carbs/fat? or less scientific
I don't beleive in bland cooking - I like lots of flavor - lots of herbs and spices and garlic and lemon juice and zest and lime juice will give you a lot of flavor bang.
you can take a basic chicken breast and marinate it in some non-fat plain yogurt, lemon juice, and curry (or cumin and coriander) and grill it and voila you've got mal's fake tandoori - and it's delicious - also good with boneless chicken thighs.
tofu i find kind of eh -- but in a curry sauce made with light coconut milk it's got some good flavor.
explore the produce department - squash, eggplant, mushrooms will give you lots of fibe and tons of flavor
