Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
Add the potatoes, onion, bell pepper & dry seasonings to the baking sheet and toss to coat. Spread in an even layer and place in the oven for 30 minutes, tossing after 20 minutes. Remove from the oven.
Meanwhile, combine the Just Egg, milk & cream cheese in a bowl. Whisk until combined & smooth.
Grease a 9x13 baking dish. Add everything from the baking sheet to the bottom of the baking dish. Top with the spinach & crumbled soyrizo. Pour over the egg mixture. Place in the oven for 45-55 minutes, or until the vegan eggs have set.
Remove from the oven and allow to rest for 5 minutes. Cut into 6 slices and serve.

Notes
You want the potatoes to be on the smaller side and for them to be uniform. If they are too big, they won't cook all the way through!
Be sure to press out all of the liquid from the spinach before adding it to the casserole.
