Easy Keto Homemade Mayonnaise and BLT

Y’all I love making my own homemade mayonnaise because I know exactly what’s in it and I love sandwiches. But I try to eat a Keto diet – high good fats, high protein, and low-carb diet as much as possible. Which isn’t easy for this carb-loving gal.

Homemade mayonnaise is really easy to make and you know exactly what is in it. Add it to a low-carb BLT and you have the perfect sandwich.

And I do love a good sandwich.

However, I don’t love the carbs in bread.

Well, I love bread, but bread doesn’t love me. So, I’m always looking for low-carb options for sandwiches.

I use lettuce often to replace bread, like lettuce wraps. But using bell peppers is another great way to make sandwiches. Especially if you want a sturdier sandwich. Bell peppers are good for you and only have only 6 grams of net carbs per serving.

They are high in vitamins A and C and are anti-inflammatory. Making them a much healthier option to bread for sandwiches.

I enjoy BLTs not only for breakfast or brunch but for lunch and dinner, too. You may not think of BLTs using bell peppers in place of the bread as a breakfast sandwich, but I think these BLTs work great for breakfast.

They are great anytime, in my opinion.

So, I hope you enjoy this homemade mayonnaise and low-carb BLT as much as I do. You can try these bacon cheese ball bites and this keto steak recipe for more high-protein, low-carb options.
