Imagine a playful yet modern app icon for 'Hello Chef,' an AI-powered recipe assistant. Incorporate a cartoon-style chef hat in a 2D, flat vector design. Consider adding the word 'Hello' in a contemporary font, perhaps with a slight tilt or curve for added dynamism. Think about how you can convey the app's purpose of helping users find and follow recipes through the icon's design. Get creative with colors and composition to make it eye-catching and memorable.
