Was I wrong or rude to offer my neighbor leftover prime rib?

I live alone and so I try not to waste food. My daughters are both vegetarians. So, about 2 months ago, there was a sale on prime roast. I never get it, but it was about 1/2 the price, so I splurged in it.

A neighbor of mine, who lives alone and is rather rigid in her ways, used to go out a lot with me. Lately she has not, although she is still friendly and texting me as I do her. I cooked the prime rib yesterday, and offered her a slice of it as I was going to freeze the rest. I had texted her this, and I got no answer although she has read it. Was this offensive to her maybe?

Just so you know, this is a bit about her. We were once in a Mexican restaurant (she was for the "wall" even though she likes Mexican food) and she mentioned a woman who was wearing close to nothing at another table and got huffy about it, as if the woman was a tart. I thought to myself, the woman could wear whatever she chooses. Other times, she has shown that she could be a but neurotic. She also seems to have a dislike for Muslims, which are a prominent group where I am.

Would you have been wary if I had offered you a slice of prime rib, or thought this was weird? I mentioned it was a lot and that I was freezing there rest of the cooked portion.
