Why add benefits of the ingredients?

Sometimes, there’s no time and we rush through the drive-thru for a meal. But when we’re at home, we can control what’s in our food.

I find that it’s important to know what we are putting into our bodies. If you feel like you’re missing out on a certain nutrient, going to food is the best option. A much better option than stocking up on pills.

This quick and easy meal will fill you with magnesium, vitamin C, vitamin A, and fiber. You can explore and add more veggies if you feel that you need different nutrients. (Keep in mind, the nutrition facts might change if you do!)

Key Ingredients

oven baked fish with vegetables ingredients- celery, tomatoes, parsley, butter, dill, red pepper, onion, garlic, mayonnaise, salt, pepper, carrots, and halibut.

Halibut is rich in magnesium, which helps to reduce the risk of diabetes. Also, it can fight against asthma and multiple myeloma.

Red peppers are anti-inflammatory and contain vitamin C, which helps to boost levels of antioxidants.

Carrots are rich in beta-carotene, which turns into vitamin A in your body. It supports eye health and is vital for immune support.

Tomatoes are filled with lycopene, which prevents sun damage to your skin. Lycopene also protects the body from the damage of free radicals.

Celery is rich in fiber, supporting your digestive system, and antioxidants that help to lower oxidative stress.

Onions are filled with organic sulfur compounds. These compounds contribute to onions’ strong taste. Additionally, they reduce cholesterol levels in your body and lower the risk of stroke.

Garlic benefits heart health and is even anti-cancer. It helps to protect the heart after a heart attack and reduces blood pressure.

Along with those ingredients, you will need mayonnaise, salt & pepper, dill, parsley, and unsalted butter.
