Quarter the tomato, de-seed the peppers and add them skin-side-up to a baking sheet.
Set your oven to broil on high, and broil these vegetables for 5-7 minutes or until the skin is charred. Let them cool completely before removing the skin.
Add these to a blender with the hazelnuts, vinegar, olive oil and spice. Purée until smooth. Set aside.
Soak the rice cakes in a large bowl of cool water for 10 minutes. The drain the water.
Put a pan with a tight fitting lid on medium heat and let it come up to temperature. Add 1/2 cup of water to the pan, make sure when it hits it immediately starts to simmer. Add in the rice cakes in an even layer and cover with the lid. Let them steam for 5 minutes to soften.
When the rice cakes are soft but not mushy, remove the lid and turn the heat down to low. Add in the romesco and stir to combine with the rice cakes. The sauce should be thin but cling to the rice cakes. Add a splash of water if you need to thin it out a bit more.
Serve warm with a healthy sprinkle of parsley on top to break up the spice. And enjoy!
