Cut and mix, for example:

• Broccoli
• Leek
• Sweet potato
• Asparagus
• Artichokes
• Onion

Add spices to your liking, f.e:

• Himalayan salt
• Cumin
• Curry
• Oregano

I put in some teaspoons of coconut oil and then I add a little bit of water. 30 minutes in the oven at 190º if you like it crunchy or add time to taste.
