Add Tikka Masala Base ingredients to a blender or food processer. While blending, slowly add 1 tbsp of water. Make sure you scrape down sides until you alll ingredients resemble a paste. Set aside.
In a large sauce pan, add coconut oil over medium high heat. Dice tempeh into small cubes then add to pan along with the Tikka Masala paste. Cook for 5 minutes while stirring regularly.
Drain the canned tomatoes then add to pan. Mash the tomatoes with a spoon and reduce the heat to medium. Add in coconut cream. Taste as you go to adjust seasonings (I always end up adding way more than listed). Simmer for 15-20 minutes stiring often until it is a thick mixture.
While the Masala base is cooking, make the coleslaw. Add all colslaw ingredients in a large bowl and stire to combine. Taste as you go to adjust. Set aside.
Warm tortillas over open flame then divide into plates. Build the tacos with a scoop of the Tikka Masala, coleslaw, avocado slices, chopped cilantro, and a bit of lime juice. Ready to serve!
