Slice two cucumbers, 1 huge red onion and 4 medium sized precooked potatoes thinly and put in an oiled round oven dish. Spread 200 ml of super light cream mixed with 4 chopped garlic cloves, 1 table spoon of dried thyme, pepper and salt. Finish with 1-2 table spoons of grated parmigiano. Put in a hot oven at 200, covered with alufoil for 60 mins. And, because tomorrow is shopping day, put some cripsy baked mushrooms on top.
