I can't stand perfectly fresh carrots, but I'm slowly building up my tolerance for them through exposure. The other thing is mayo, and that's not going to change, which is for the best in my opinion. I'll eat and enjoy almost anything- I'll even eat the carrots... it just the enjoying them part that's going to take a bit of work.
I buy processed meat of 2 kinds:
Dinner sausages that are of a hand-made-this-morning variety.
Breakfast sausages, salamis and various Italian cold meats hand-made by Fra' Mani.
As far as olives, go try the Cerignola kind first. Either DeCarlo or Seggiano labels.
(And yes, all of that stuff is efing expensive )
I do agree on duck meat and peanut butter. That shyt isn't edible in my book.
