Why Diabetes Friendly?
- Low-Glycemic Ingredients – Lentils and oats provide complex carbs that digest slowly and reduce blood sugar spikes.
- Fibre-Rich – Lentils, zucchini, and oats are all excellent sources of fibre that help improve insulin sensitivity.
- Moderate Carbs per Serving – At approximately 14–16g net carbs per serving (without rice), it's easier to fit into a balanced diabetic meal plan.
- Baked, Not Fried – Lower in fat and calories, with no added oils from frying.
- Glucose-Balancing Fats & Protein – Egg, sesame oil, and lentils contribute protein and healthy fats to slow carbohydrate absorption.
- Customizable Glaze – You can reduce or swap the maple syrup for a low-carb sweetener to further lower the sugar content.

Cooking Tips
- Dry the Zucchini Thoroughly – Use a clean towel or paper towels to squeeze out excess moisture to prevent soggy meatballs.
- Mash Lentils Well – Leave some texture, but enough mash to help bind the mixture.
- Make it Gluten-Free – Use certified gluten-free oats and tamari instead of soy sauce.
- Vegan Option – Replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water).
- Crispier Texture – Broil for 1–2 minutes at the end if you prefer a slightly crisp outer layer.
- Make Ahead – Shape and chill the mixture ahead of time for easier prep during busy nights.
