1.Grandpa : salmon ( because dad is allergic with fish and the clue said the person who call salmon will share some of it with his wife : the wife is grandma  ).

2Grandma : fish and chips ( grandma did not order lasagna )

3.Dad: chicken strips ( because none of the males : dad , grandpa and josh ordered a dinner that contained pasta , none of the adult ordered hamburger and dad is allergic with fish ) 

4.Mom : lasagna ( the person who order spaghetti younger than person who order lasagna ) 

5.Josh : hamburger ( None of the adults ordered hamburger -> kids will order hamburger , none of the males ordered dinner contained pasta ).

6.Becca : Spaghetti ( the person who order spaghetti younger than person who order lasagna ) 

* Person in the family order different food ( not like each other ) 

Thank you !
