Me again. Sorry for stream of posts. This one is answering the question in the thread title!
A day of experimentation. Two successes, one near miss.
Lunch - M&S Serrano ham and manchego cheese rollitos.
Afternoon snack - not very caramelised high fibre chocolate bar.
@shelley262 I used your recipe (minus inulin and psyllium husks) and added in some chopped almonds and macadamias and 50ml double cream with the chocolate. Got 11 bars @1.6g carbs each. Brittle rather than chewy.
Dinner - pan fried salmon in garlic and lemon butter sauce and pointed spring cabbage followed by lemon zucchini cake with extra thick double cream. Zucchini cake was a smaller one and the best yet. Halved all ingredients except the lemon, which I kept constant. Salmon based on this recipe:
