Weird...
Can you make a photo of this strange unknown matter, just to be sure ?
And... is your kitchen at the right or the left side of your entrance ? (assuming that you enter in your apartment)
Let's make some theories : Ameer is so fond of you that he can't do anything but dream of you at night. As he find you so yummy, he goes sleepwalking straight to your house, enter your kitchen to make a cheese/bacon sandwich with pickle supplement and BBQ sauce. He eats you so passionately (read : he eats the
sandwich, ofc) that some scraps of bacon stuck on his cheek fall down after he has done his little affair and that he returns back to his home
(some people can be rude when they love too much).
And so, the explanations of those little pieces of meat, QED.
