"Create a healthy diabetic-friendly pastry or tart recipe, such as a berry galette or almond flour scones. Must be low glycemic index and use alternative flours like almond flour, coconut flour, or whole oat flour instead of refined white flour. Must be sugar-free or low-sugar using diabetic-safe sweeteners like erythritol, stevia, allulose, or monk fruit only; do not use honey, maple syrup, or white/brown sugar. Include healthy fats and fiber such as ground flaxseeds, chia seeds, nuts, and coconut oil or butter in moderation. Provide exact measurements, clear step-by-step instructions, and estimated net carbs per serving."
