How do you feel about,and do you know anyone that passes off their sloppy leftover food and second hand items as "gifts"?

I have this “friend”, ( I think she considers me more of a friend than I do her ) that has this weird habit of bringing me her crappy leftover food and presenting it as some sort of amazing “gift”. lol
She also gives old and defective items to others and it is SO obvious to me that really, her “gifts” are more about just unloading the crap she can’t bear to throw away. I was sick last week and this woman shows up with 4 day old tuna casserole, a bag of black bananas, top ramen and a can of canned Salmon. She then proceeds to dance around my kitchen all excited, telling my all the ways I can “enjoy” her bountiful harvest! Really? I find it so insulting, considering she has about 500k in the bank and while I am not as well off as her I am certainly not a charity case by any stretch of the imagination. Last year she “gifted” me her leftover ham carcass and gave my daughter and her boyfriend a filthy, dirty, ancient microwave for their new apartment. I am really starting to hate this woman. haha It is just so OBVIOUS that she is “giving” all of her unwanted crap. Infact, funny enough, she had just told me that she had cleaned out her fridge and freezer and then, passes off her black bananas to me, under the guise of bringing me some stuff when I was home sick. How would you handle this, just keep smiling and being polite or straight up start questioning her whenever she says “I have something for you!”
Personally I think I am going to start grilling her on just what she has in mind and then telling her,“No thanks, I don’t want that and won’t use it.”
