Make a batch of wholemeal pastry and line a 20cm tart tin - instructions to follow.
add the olive oil to the saucepan, and put on a low heat, at the same time put a few inches of water into a steamer pan and heat the water so it's ready for the broccoli.
peel and chop the onions in slivers & add to pan and saute along with the sliced garlic.
Slice the peppers into thin strips and cut in half add to pan....
slice the mushrooms in half, and then into slices and add to the same pan & continue to sautee
cut the broccoli into quite small florets - cut each main floret into at least 4 smaller pieces and put on to steam for 4 to 5 minutes. Very important not to over cook.
Cut the baby plum tomatoes in half. When the onions, peppers and mushrooms are nicely cooked, but not mushy, add the baby plum tomatoes & part cooked broccioli and stir to mix. Then turn the heat off. Turn the oven on at this point & set to 180°C FAN or 190°C convection.
tip all the veggies into the pastry case and shake level them.
In between all this, add all the other ingredients from the sauce section to your blender.
Then process until you have a quite sloppy, liquid that can be poured, but isn't too runny.
Pour the liquid into the flan case......
It should come right to the top, but may need a little gentle shaking to get it to fill all the gaps at the bottom.
Sprinkle the roughly crushed cashews on top - you can add a few chilli flakes if you like too.
Bake for 45 minutes at 180°C (fan) or 190°C if convection oven. Check with a cake probe that it's set in the middle, it shouldn't be runny, but can be sticking to the probe.
When finished it should look like this - slightly browned on top.
Removed from the flan case it will look like this.
