Great touches!
Such a food fan here and you've covered some of my favourite ingredients!
Onion: Beautiful colour scheme and nice reflection from the table top. Nice and appropriate font gives the photo a heightened sense of sophistication. Slight flare on the onion but that's a minor problem, easily rectified with diffused lighting.
Garlic: Again, some really nice touches but as Ruthbaby pointed out, not the best looking garlic for the shoot (snobs we are!) and colour graduation not as effective as the first.
Chilli: Like it alot. Perhaps move the chilli slightly so we could see more of it. Different angles might work better with this shot.
Overall, one of the more inspiring food shots I've seen in a while. Keep them coming!
Thanks for sharing.
