There is debate about miner's lettuce, not sure if there is a really good scientific research done on it's edibility. I know that I don't eat too much of it. A salad of it is fine, as well as a side of cooked greens on my plate. I do however, sense physically that there is something to the reports of it being toxic or high oxalates in very large doses, so I don't recommend making green smoothie after green smoothie of miner's lettuce. Many wild plants are like this, it's something that I can sort of taste or sense now. Oxalates are also intensified in plants when the weather is really hot, dry, or some other stressor in the plant. I can hardly eat my chard growing in the middle of the summer for this reason. Wild plants, because they often are growing in harsher environments than in our tended garden, often do the same thing.
That might explain why feral rabbits don't eat miner's lettuce (but we are talking about Claytonia perfoliata right?). What are you meaning by very large doses? I think smoothies can be problematic for wild foods because you lose the taste and triggers that come from chewing (loss of benefit, and more likely to have side effects).
