Starving myself on this diet?

i feel like im starving myself on the food plan im on..i dont want to say diet because its not really a diet..its just the healthiest food choices i can make. but we have a lot of junk food at home and i already ate all of the salad and vegetables and fruit and now all there is is bread..frozen pizza and frozen burritos ..lots of chips and i also need stuff to pack for school lunch and idk what to do im so nugry but i refuse to eat unless its healthy. and i refuse to drink anything thats not water
