When I saw 'make thin patties' I thought great - a good stuffed burger recipe. Wrong! I must agree with the review of 'chef d'. However, if the recipe advised:- saute the onion etc., place a tblspn. of these ingredients on a thin pattie, add a slice of cheese, place 2nd. pattie on top & seal, then put in bun - that would be different, (I think).
