Heat 2 tablespoons avocado oil on medium high in a large skillet or wok. Add diced onion and frozen vegetables, and sauté until onions are almost translucent, about 3 minutes. Move the vegetables to the side of pan. Crack eggs into pan and scramble with a spatula until cooked through and fully scrambled.
Add 4 cups cooked rice and 4 tablespoons butter. Cook for 5 minutes and stir frequently. Add 4 tablespoons soy sauce and cook 1 additional minute. Pack fried rice firmly into bowls to keep hot.
For the Chicken and Vegetables (Made Simultaneously)
For the chicken: Heat 1 ½ teaspoons sesame oil and 1 tablespoon avocado oil in same skillet or wok used for fried rice. Add chicken, 3 tablespoons soy sauce, 1 tablespoon butter, lemon juice, salt, and pepper to skillet. Cook chicken until it is no longer pink, about 5-7 minutes. Stir only once or twice so chicken will brown.
For the vegetables: In a separate large skillet or wok, heat 1 ½ teaspoons sesame oil and 1 tablespoon avocado oil on medium high heat. Add sliced onion, baby bella mushrooms, zucchini, 1 tablespoon butter, 1 tablespoon soy sauce, salt, and pepper to skillet. Sauté until vegetables are tender, about 6-8 minutes.
For the Mustard Sauce
Lightly toast sesame seeds if desired. (See note.) Blend sesame seeds, dry mustard, 2 teaspoons honey, 4 tablespoons soy sauce, half and half, hot water, and minced garlic in blender.
Recipe Notes
For the best fried rice: Do not cook rice immediately before making fried rice. Leftover or precooked rice from the store works best.
For mustard sauce: Lightly toasting sesame seeds will enhance the flavor, but it is not necessary. Mustard sauce can be made ahead of time and stored in the refrigerator.
To make grain-free: Substitute rice with cauliflower rice.
