Soak sunflower seeds and cashew nuts overnight
Drain the cashews and reserve the soaking liquid. Place soaked cashews, garlic, nutritional yeast, white wine (or dijon mustard), and lemon juice in a food processor or blender. Blend until all ingredients are combined. Slowly add reserved water 1 TB at a time, until cashew cheese reaches desired consistency. Place in fridge and allow to chill up to 1 hour to allow flavors to settle.
If preparing Cilantro Cream sauce, mix all ingredients in a small bowl chill up to 1 hour.
For Sunflower Taco Meat, drain sunflower seeds and combine with all ingredients in a blender or food processor. Pulse ingredients together, stopping frequently to scrape sides. Final product should be fairly chunky with some seeds still intact.
Build tacos by placing sunflower taco meat in collard leaf, then top with desired ingredients. Finish off with cashew cheese and cilantro cream.
Preparing batches of the taco meat and cashew cheese saves time to quickly assemble future tacos.
