Yes Chenopodium triandrum which you can recognise easily by the trowel-shaped leaves lacking any addition lobing. When in fruit this species has succulent red fruit - our other species in what had been Einadia have scarcely succulent or even dry fruits.
Einadia was placed into Synonym within Chenopodium by Fuentes-Bazan et al. (2012)
See: Fuentes-Bazan, S.; Uotila, P.; Borsch, T. 2012: A novel phylogeny-based generic classification for Chenopodium sensu lato, and a tribal rearrangement of Chenopodioideae (Chenopodiaceae). Willdenowia 42: 5-24.
That paper and papers cited therein also split up what we have called Chenopodium here into a number of genera, e.g., Dysphania, Oxybasis, Blitum etc.
