Could try blending a little red onion in at a time? But I didn't tell you that lol. Mine wouldn't eat deer when we first married but I blended until it was pure venison goodness and then told her what she'd been eating and all was well haha . She just hadn't had it cooked right before.Her parents didn't make her eat vegetables when she was growing up so she never acquired a taste for them whereas my mom always had a garden and fresh vegs on the table for dinner each night
