• 2 bell peppers (any color), sliced
• ½ cup soy sauce
• 2 teaspoons sugar
• 1 teaspoon ground ginger
• 2–3 tablespoons cornstarch
• Salt and pepper to taste

Tools You’ll Need

• Slow cooker (4–6 quarts)
• Large skillet

Ingredient Additions & Substitutions

• Use chicken broth instead of bouillon
• Add mushrooms for extra umami

Step-by-Step Instructions

1. Prepare the Beef

Slice the sirloin into thin strips. Season lightly with salt, pepper, and garlic powder.

2. Brown the Beef

In a large skillet, heat vegetable oil over medium-high heat. Sear the beef strips until browned (they don’t need to be fully cooked). Transfer to your slow cooker.

3. Make the Sauce

Dissolve the beef bouillon cube in ¼ cup hot water. Stir in:

• soy sauce
• sugar
• ginger

Pour over the beef.

4. Add Veggies

Add sliced peppers and onions on top.

5. Slow Cook

Cook on:

• Low for 6–7 hours, or
• High for 3–4 hours

The beef should be tender and the veggies soft.

6. Thicken the Sauce

In a small bowl, whisk cornstarch with ¼ cup cold water. Stir into the slow cooker. Cook on high for an additional 20–30 minutes until the sauce thickens.

7. Serve Hot

Serve over rice, mashed potatoes, noodles, or even cauliflower rice for a low-carb option.
