Rainbow Unicorn Sweet Potato Sushi [Vegan, Gluten-Free]




  • 2 cups uncooked sushi rice
  • 1 avocado
  • 1 bell pepper
  • 1 cucumber
  • 1 sweet potato
  • Turmeric, to make yellow
  • Beet powder, to make red
  • Spirulina or matcha, to make green
  • 1/2 teaspoon baking soda
  • 1/4 piece purple cabbage, to make purple
  • 5 sheets nori
  • 1-2 tablespoons sugar
  • 1/4 cup rice vinegar
  • 1 teaspoon gochujang, to make orange (optional)


To Make the Rice:

  1. Cook the sushi rice and place it in a bowl to cool and add the rice vinegar and sugar to your own taste. Mix it in using a wooden spoon (this will help prevent the rice from breaking).
    To make each color, you take a shallow bowl and put about 1/2 cup of rice and mix in the food coloring. Keep in mind that you just want to color the rice, so don’t add too much of each food coloring otherwise you might alter the taste too much. For red
  2. For red, use a bit of beet powder For orange, use a mixture of turmeric and beet powder or a small amount of gochujang. For yellow, add a little bit of turmeric For green, use a little bit of spirulina and a pinch of turmeric. For blue and purple, read below.

To Make Blue and Purple Rice:

  1. Boil 1/4 piece of chopped cabbage in about 3 cups of water for about 30 minutes or until you’re left with about 1 cup of water. Use this water to cook 1/2 cup of sushi rice and save about 3 tablespoons of the purple water to make the blue food coloring.
  2. Now you’ve got your purple rice use some of the remaining white rice you made to make blue. Add about 1 teaspoon of baking soda to the purple water and it will turn blue, now add this to the sushi rice and mix it well.

To Assemble the Sushi:

  1. Chop your sweet potato in strips and roast these in a preheated oven on 390°F for about 20 minutes.
  2. Now, chop the remaining ingredients into strips.
  3. Now get a bamboo roller and cover it with some plastic wrap to keep it clean. Add a sheet of nori and place strips of rice until you’ve got all the colors and top this with the filling. Now, roll the sushi and wet the end with a bit of water to make it sticky and place it on a platter or chopping board. Once you’ve rolled all your rolls, wet a sharp knife and slice your rolls.

Meyer Lemon Coconut Cream Tarts With Mint and Lavender [Vegan, Raw, Gluten-Free]

To make the crust: put the oats and almonds into a high speed blender and blend until it turns into a thick, slightly crumbly paste. If needed or desired, add a little maple syrup, then press into two tartlet molds or whatever shapes/molds you like. Put in the fridge. To make the lemon coconut cream: put the coconut and cashews into your high speed blender and blend until it turns into a thick paste/butter. Stir in a 1/4 cup lemon juice and the maple syrup until evenly combined (or blend it in). If you'd like more lemon flavour, add more lemon juice! I like mine quite tart - no pun intended, seriously - so I used a full 1/2 cup. Spread this mixture evenly into your crusts, then let them sit in the fridge overnight or for at least a couple hours so the flavours can get to know each other. Garnish with mint, basil, lemon zest, maple syrup or whatever else you like! Life is good!
