Tips from the EatingWell Test Kitchen

• We use cremini mushrooms in this quiche, but any variety of mushrooms will work. Try swapping them out for or combining them with other varieties such as oyster, shiitake or maitake mushrooms.
• You can use broccoli florets from a bag or cut them from a broccoli crown. Either way, make sure you cut them small enough (not bigger than ½ inch) so they cook evenly and in the allotted amount of time.
• Don’t stir the veggie mixture into the egg mixture straight from the stove. Cook the veggies first, then let them cool while you mix the custard. Adding them when they’re too hot could scramble the eggs.

Nutrition Notes

• Eggs provide the bulk of the protein in this quiche, but that’s not all they deliver. Egg yolks are a good source of vitamin B1 and vitamin D, which can help support energy. They’re also rich in choline, which is an important nutrient for memory and supporting brain health. 
• Broccoli contains sulforaphane, a compound that has been linked to reduced risk of various cancers, including breast, colon and skin cancers, as it can inhibit cancer cell growth. Broccoli is also a good source of vitamin C for immune health and vitamin K for bone health. 
• Mushrooms are a good choice for gut health, as they act as prebiotics to help feed the good bacteria in our gut. Some light-exposed mushrooms also provide vitamin D (check the package), which helps keep our bones healthy and strong. 
• Spinach contains compounds known as nitrates that work to lower blood pressure and improve blood flow in the arteries. Spinach also contains iron, a key nutrient for supporting energy levels and carrying oxygen throughout your blood.
