Mine would also have loved your veggie garlicy creation
I see no harm with it at all, you only need to avoid/have caution with salt really (and the other few no-go foods, honey, sugar, whole nuts, raw fish...)
Any food can cause a reaction though, mine devoured some oven baked potato wedges seasoned with masala but almost instantly got a skin rash on face and hands, anywhere the spice had touched, it did not react inside him (no vom or diarrhoea) but the skin reaction wasn't nice.
Lovely to hear your LO is enjoying his experience with solids
