Method: Sunday Suppers: 30-Minute Sriracha Pepper Steak

Step 1: Prepare the Sauce
In a small bowl, combine the minced garlic, brown sugar, soy sauce, water, balsamic vinegar, corn starch, and sriracha hot sauce. Whisk until smooth and set aside. This sauce is the star of your Sunday Suppers: 30-Minute Sriracha Pepper Steak, so make sure it’s well mixed.
Step 2: Sauté the Steak
In a large skillet, heat 1 tablespoon of sesame oil over medium-high heat. Add the flank steak strips and sauté for about 3-4 minutes, or until browned and cooked through. Remove the steak from the skillet and set aside.
Step 3: Cook the Vegetables
In the same skillet, add another 1/2 tablespoon of sesame oil. Toss in the sliced red, orange, and yellow bell peppers, along with the sliced red onion. Sauté for about 3-5 minutes until they are tender yet still crisp.
Step 4: Add Aromatics
To the vegetables, add the grated ginger and minced garlic. Sauté for an additional minute until fragrant.
Step 5: Combine and Simmer
Return the cooked flank steak to the skillet and pour the sauce over everything. Stir well to combine and let it simmer for about 2-3 minutes until the sauce thickens slightly.
Step 6: Stir in Spinach
Add the fresh baby spinach to the skillet, stirring until wilted, about 1 minute. This adds a pop of color and nutrients to your dish.
Step 7: Serve
Serve your Sriracha Pepper Steak over your choice of rice, quinoa, or couscous. Enjoy the vibrant flavors and the joy of a quick yet delicious Sunday supper.
Fresh Takes Through the Year

- In the summer, add fresh corn and zucchini for a seasonal twist.
- In the fall, swap out the bell peppers for seasonal vegetables like butternut squash.
- In winter, include hearty greens like kale or Swiss chard for added nutrition.
- For a lighter option, replace the flank steak with chicken or tofu.
Watch Outs & How to Fix
- Too Spicy: If the dish is too spicy for your taste, add a little more brown sugar or a splash of coconut milk to tone it down.
- Overcooked Steak: Make sure to keep an eye on the steak while cooking; overcooking can make it tough. Thin strips will cook quickly.
- Too Thick Sauce: If the sauce becomes too thick, add a splash of water to loosen it up while cooking.
- Vegetables Too Soft: If you prefer your vegetables with a bit more crunch, reduce the sauté time.
Cooling, Storing & Rewarming
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm in a skillet over medium heat until heated through. You can also use the microwave for a quick reheat, though the skillet will help retain the texture of the vegetables and steak.
