High-protein
Swap the cheddar for crumbled reduced-fat feta or cottage cheese and add 1/4 cup cooked, crumbled turkey sausage — bumps protein without adding many carbs.
veganVegan
Replace egg whites with 1 1/2 cups silken tofu blended until smooth, and use a plant-based cheddar shred; the texture stays tender and the dish becomes entirely plant-based.
low oilLow-oil
Line the muffin tin with parchment paper cups instead of greasing with oil to reduce fat; the muffins still release cleanly and stay moist from the vegetables.
jainJain
Omit the onion and garlic powder (use asafoetida/hing for flavor) and replace cheddar with a pinch of rock salt; this keeps the recipe compliant with Jain dietary restrictions.
