I was going to say a weed. I think tomatillas have smooth stems, if I recall correctly, yours has bristles on it. Rub a leaf and smell it. Usually a weed leaf has its own particular odor and does not smell appealing, either. Nor does it smell like a vegetable... I have weed seeds quite frequently germinate and I am constantly plucking off a leaf to smell it before I pull the whole thing out, just to make sure.
