Ingredients Overview

Let’s break down what goes into each part of your bento box — and how to keep it balanced, tasty, and lunchbox-friendly.

Teriyaki Tofu

• Firm or Extra-Firm Tofu: Best for crisping and holding its shape. Press it well to remove moisture before cooking.

• Cornstarch: Lightly coats the tofu for extra crispness when pan-fried.

• Oil: Use a neutral oil like avocado or vegetable for frying.

• Homemade Teriyaki Sauce: Quick to make and much cleaner than bottled versions.

Teriyaki Sauce (Vegan)

• Soy Sauce or Tamari: Salty umami base.

• Maple Syrup or Brown Sugar: Sweetens and thickens when reduced.

• Rice Vinegar: Adds tang to balance the sweetness.

• Ginger & Garlic: Aromatic and savory.

• Cornstarch Slurry: Thickens the sauce to a glossy glaze.

Grain Base

• Brown Rice: High-fiber, chewy, and satisfying. Cooked ahead or from a frozen packet.

• Other Options: White rice, quinoa, or cauliflower rice.

Bento Sides (Classic & Fresh)

Choose 2–3 sides for variety and visual appeal:

• Edamame: Steamed and salted.

• Cucumber Slices or Pickled Cucumber: Adds crunch and freshness.

• Steamed Broccoli or Snow Peas: For color and fiber.

• Cherry Tomatoes: Juicy and vibrant.

• Fruit: Mandarin orange slices, apple wedges, or grapes.

• Optional Treat: A piece of nori-wrapped rice ball or a small mochi for dessert.

Step-by-Step Instructions

1. Press & Cube the Tofu

• Use 1 block (14 oz) of extra-firm tofu.

• Press for at least 10–15 minutes to remove moisture (use a tofu press or wrap in a towel with weight).

• Cut into bite-sized cubes (about 1-inch).

2. Cook the Tofu

• Toss tofu cubes with 1–2 tsp cornstarch for extra crispness.

• Heat 1–2 tbsp oil in a nonstick or cast-iron skillet over medium heat.

• Add tofu in a single layer and pan-fry 3–4 minutes per side, flipping until golden and crispy on all sides.

• Remove from heat and set aside on a plate.

3. Make the Teriyaki Sauce

In a small saucepan, whisk together:

• 1/4 cup soy sauce or tamari

• 2 tbsp maple syrup or brown sugar

• 1 tbsp rice vinegar

• 1 tsp grated fresh ginger

• 1 clove garlic, minced

• 1/2 tsp sesame oil (optional)

• 1/2 cup water

• 1 tsp cornstarch + 1 tsp water (slurry)

Bring to a simmer, then stir in the cornstarch slurry. Simmer 1–2 minutes until thick and glossy.

4. Toss Tofu with Sauce

• Return tofu to the skillet or a clean pan.

• Pour over the teriyaki sauce and toss to coat evenly.

• Cook 1–2 minutes until everything is sticky and glazed.

5. Assemble Your Bento Box

In a lunchbox or meal prep container:

• Add 1/2 cup brown rice to one section.

• Spoon teriyaki tofu over or beside the rice.

• Add 2–3 side items: steamed broccoli, edamame, cucumber slices, orange wedges, etc.

• Optional: sprinkle with sesame seeds, scallions, or nori strips for garnish.

Let cool slightly before sealing and refrigerating.
