How to eat healthily during pregnancy?

i am 11 weeks pregnant and living with my husband, father in law n brother in law.thingy is, they eat malay and indian food most of the time.these foods r quite rich considering the gravy n fried stuff. they also do not eat a whole lot of vegetables so usually when i cook, i'll be the only one eating the vege. somehow or other no matter how little vege i cook, it will still go to waste.how can i ensure that i eat healthily n my diet actually helps my pregnancy. i am already making myself take folic acid,drinking formula for pregnant moms and drinking 2 big gles of juice a day. sometimes i munch on pears. hope someone can help me.thanx in advance.
