Heat oil in a skillet over medium heat. Add garlic and spinach and cook until the spinach is wilted.
Add cooked spinach and garlic to a mixing bowl along with the rest of the ingredients. Mix until combined.
Add egg batter to an 8x8 baking dish lined with parchment paper. Bake for 25-35 minutes. You want the center to be set and not gooey. I have an old apartment oven and baked mine for 35 minutes.
Let cool for 10 minutes. Cut into 6 evenly sized bars and serve.
Notes
This makes 6 bars. 1-2 bars make a good serving depending on how hungry you are.
