I am by no means a baker - I like to leave that to the pros. In the summer when fruit is pure magic and little to no sugar or "extras" are needed, I break out of my anti-baking mentality. This crumble is what I like to call "baby baking" or "baking light". Precise measurements are not 100 percent required, and the ingredients are adaptable, depending on what fruit you happen to have on hand or what is in season.
