Pre-heat your oven / airfryer to 200 degrees celcius. On a baking tray, season your beetroot with salt, pepper + olive oil. Do the same with the garlic bulb, then cover with foil. Roast for 30 minutes, or until soft + tender.
Meanwhile, slice the onion + sauté in a frying pan on a medium heat with a splash of olive oil until caramelised (10-15 mins).
Add the beans + ½ their liquor , stirring well. Lower the heat + allow to cook for a further 5-10 mins.
Remove the skins from the beetroot, then place in a blender. Squeeze out the roasted garlic cloves, then add the nutritional yeast, a splash of olive oil + the remaining bean liquor. Blend until smooth, seasoning to taste with salt, pepper + a squeeze of lemon juice if you like.
Pour into the beans + mix well. Check for seasoning + cook for a further couple of minutes.
To serve, toast some bread, then spoon the beans into bowls. Top with crumbled feta, chopped fresh parsley, lemon zest + olive oil - enjoy!
