How does the vagabond eat his bread?

The vagabond claims to love his life, with only heaven above him and the road below. He says that he likes to sleep out under the stars and "dip" his bread "in the river" (line 6). I think it is unlikely that he actually dips his bread in the river; it's more likely that he eats his bread while he sits next to the river, enjoying its beauty. He obviously loves nature, as he prefers it to wealth, companionship, and even warmth and comfort, so it makes sense to me that he would forego taking his meals near other people or in cafes, for example (and he probably doesn't have the money for that). Dipping his bread in the actual river would probably not improve its flavor, but eating what he comes by in the company of nature, sitting by the riverside, sounds idyllic and in line with his priorities.
