Preheat oven to 350 degrees.
Heat olive oil a skillet over medium-high heat. Once hot, add garlic and onion. Sauté until softened and fragrant, about 2 minutes. Add broccoli and sauté for another 2 minutes, or until slightly tender.
In a large bowl whisk together chickpea flour, nutritional yeast, water, vegetable broth, turmeric, salt, and pepper.
Grease or spray muffin tins, then divide sautéed broccoli mix into the cups. Make you reserve some because you’re dividing the veggie mixture between 18 frittatas.
Measure ¼ cup of batter and pour into muffin tin on top of veggie mixture. If adding cheese, drop a few shreds into each cup now.
Bake frittatas for 25-30 minutes. Repeat until all the batter is gone.
Let the mini frittatas cool for 10 minutes before serving. Store leftovers in the fridge for 7 days, or freeze. Pop leftovers in microwave for 30 seconds before eating, or enjoy cold.
