To eat or not to eat?

my dad is making a beef stew for dinner but i can't eat it! i have managed a week as a vegetarian (i know it ain't a lot) but i'm proud i can do it. if i don't eat this stew my parents will be angry and say to me go hungry then and they won't let me get and other food. should i go hungry or should i take the beef out of the stew and eat the rest (vegie and potatoes?) x thanks x
