Can I make this without eggs?

Yes! Just make the hash with the sweet potatoes, sage, sausage, and chard and don’t top it with an egg. It’ll be great as is!

Can I make this vegetarian?

Sure! Use beans (cannellini or another white bean, or even black beans, would work well) instead for a fiber-rich, vegetarian protein option.

I don’t want to use 2 pans. Can I cook the eggs right in the hash?

Yes, you can. Just make dents or wells in the sweet potato mixture where you’ll drop each egg. Cook the eggs to your liking. It may take longer to cook them in the hash this way, so you could cover the pan too. Just be aware that covering it might make the egg yolk cook fully too so that it isn’t runny.
