Cook the spinach in the microwave or stove top, according to package directions. Drain the spinach, then use paper towels to squeeze out any excess moisture. *See note

In a large bowl, combine the drained spinach, mayo, sour cream, vegetable mix, green onions, and lemon juice, if using. Stir until well combined. Cover and refrigerate for at least 2 hours or until ready to serve.

When ready to serve, use a bread knife to cut a circle around the outside of the bread loaf, angling your knife towards the center, and leaving about a half inch around the sides and the bottom. Remove the center, then use the knife and/or your fingers to remove any extra pieces.

Spoon the dip into the center of the loaf, then cut the remaining bread into cubes for dipping. Serve with veggies, bread, and/or crackers for dipping.
