Preheat your oven to 400°F (200°C). Wash the sweet potatoes thoroughly and pat them dry. Pierce each potato several times with a fork to allow steam to escape. Place them on a baking tray and roast for 35–45 minutes, depending on their size, until they are tender when pierced with a knife. Remove them from the oven and allow them to cool until easy to handle.
Slice each sweet potato in half lengthwise. Carefully scoop out most of the flesh, leaving a layer of about ¼ inch attached to the skin so the halves hold their shape. Reserve the scooped-out flesh for another meal, such as mashed sweet potatoes or soup. Brush the inside and outside of each potato half with olive oil. Sprinkle with salt, black pepper, smoked paprika, and garlic powder.
Arrange the potato halves cut-side up on the baking tray. Return them to the oven for 10–15 minutes. For extra crispiness, turn them over for the final 3–5 minutes, watching carefully to prevent burning. The edges should be golden brown, and the skins should feel firmer.
Add the crumbled feta, softened cream cheese, Greek yogurt, olive oil, lemon juice, and optional garlic to a food processor. Blend for 1–2 minutes, scraping down the sides as needed, until the mixture becomes creamy and fluffy. If the feta mixture is too thick, add water one teaspoon at a time until it reaches a smooth, spreadable consistency. Taste before adding extra salt because feta is naturally salty. Refrigerate briefly while preparing the other toppings.
Cut the avocado in half, remove the pit, and scoop out the flesh. Dice it into small cubes and place them in a bowl. Gently toss with lemon or lime juice, chopped cilantro or parsley, a pinch of salt, and black pepper. Avoid overmixing so the avocado retains its shape.
Add the honey to a small heatproof bowl. Warm it gently in the microwave for about 10–15 seconds or in a small saucepan over low heat until it becomes runny. Stir in the chili flakes, lemon juice, and optional smoked paprika. Let the mixture stand for 3–5 minutes so the chili flavor infuses into the honey. Taste and adjust the heat by adding more chili flakes or more honey as needed. Do not boil the honey.
Arrange the crispy sweet potato halves on a serving platter. Spoon or pipe the whipped feta into each skin, spreading it evenly without overfilling. Add a generous spoonful of diced avocado on top. Drizzle the chili honey over each potato half, allowing a little to run over the feta and avocado.
Finish with chopped parsley or cilantro, optional sesame seeds, extra chili flakes, and a light drizzle of olive oil. Serve immediately while the potato skins are warm and crispy and the whipped feta is cool and creamy.
