@ElainaA Thanks for your kind offer however my neighbors would be more than happy to have me harvest their purslane 
On a more serious note give it a try. Add the leaves as a component of a salad. They have a mild succulent texture and a citrusy flavour. I had the same thinking outside the 'acceptable food' box.
And yes the endemic blight in this area was non-existent this season however I still suffered from powdery mildew despite the drought conditions.
@Bhukhhad I have tried them sautéed with other greens such as beet and chard and they work very well.
@TicTac I use the Ministry of Agriculture, Food and Rural Affairs Publication No. 505 'Ontario Weeds' as my go to. There are also many U Tube Foraging sites that go into detailed identification (although it would take a lot of wishful thinking to substitute another plant for Purslane). It is quite distinct. Nutritionally it contains high levels of omega 3 fatty acids. Lots of info online.
