Sometimes the smallest details can completely change how children experience food. Turning a simple sandwich into a playful character instantly makes lunchtime feel more inviting — especially during themed weeks like Ocean Week, Beach Week, or Animal Studies.
These crab sandwiches are an easy, no-fuss way to bring learning through play into your kitchen. They work just as well for lunch as they do for snack time and can be made with ingredients you likely already have on hand.
This activity pairs beautifully with ocean-themed books, sensory play, or dramatic play during your homeschool rhythm.
Why Themed Snacks Work for Kids
Themed snacks:
Encourage hesitant eaters to engage with food
Create positive associations with meals
Support conversation and storytelling
Reinforce weekly learning themes
Help transitions feel smoother during the day
For young children, food presentation can be just as impactful as taste.
Ingredients
You can adjust ingredients based on dietary needs or preferences.
For the Sandwiches
Sandwich rolls, slider buns, or halved croissants
Sliced cheese (cheddar or American work well)
Deli meat or sandwich filling of choice
Turkey
Ham
Chicken
Or a vegetarian alternative
For the “Crab Eyes”
Adhesive-backed googly eyes
Toothpicks (adult prep only)
Optional Sides
Fruit, crackers, or veggie sticks to complete the plate
Optional Secret Sauce (Highly Recommended)
This simple spread adds flavor while keeping ingredients familiar for kids.
Mayonnaise
Finely chopped shallots
A light sprinkle of Lawry’s Garlic Salt
Mix to taste and spread lightly on the inside of the sandwich before assembling.
How to Make Crab Sandwiches
Slice your rolls or croissants in half.
Spread a thin layer of the secret sauce on one or both sides of the bread.
Add cheese and your preferred sandwich filling.
Gently press the sandwich closed, leaving the sides slightly open to resemble crab “claws.”
Attach adhesive-backed googly eyes to the tops of toothpicks.
Insert the toothpicks into the sandwich to create the crab’s eyes (adult step).
Arrange on a plate or tray and serve.
Simple, playful, and quick.
How Kids Can Help
Depending on age, children can:
Choose the sandwich filling
Spread the sauce (with supervision)
Layer cheese and meat
Help assemble the sandwich
Name the crab or make up a story
