Why You’ll Love This Recipe
Whether you’re juggling weeknight dinners, prepping meals for the freezer, or trying to stick to a special diet, this make-ahead Tex-Mex filling is your new best friend. It’s hearty, full of protein and fiber, and naturally gluten-free. Plus, it’s easy to adapt for Low FODMAP, low nickel, dairy-free, and top 8 allergen-friendly diets.
Meal prep lovers: this one’s for you! The recipe makes multiple portions and holds up perfectly in the freezer. It’s also kid-friendly, great for lunchboxes, and ideal for busy weeknights when you want something nourishing without the fuss.
I love keeping portions in the freezer because it makes a filling, satisfying meal in minutes. Just grab a bag, defrost it in the microwave (about 1.5–2 minutes, stirring halfway), and prep a few fresh ingredients while it heats. It’s quick, easy, and so good that you’ll be going back to the freezer for seconds!
Substitutions & Allergy-Friendly Considerations:
This Tex-Mex filling is easily customizable depending on your dietary needs:
- Low FODMAP:
- Black beans are low FODMAP in servings of 40g per meal (about 2 tablespoons) which is why this recipe uses a small amount – but omit this option if you have a sensitivity with GOS or fructans.
- Another alternative to black beans are canned lentils (rinsed well) – which are low FODMAP in servings of less that 1/4 cup per meal.
- For the spring onions, make sure to use only the green tops to keep it low FODMAP
- Make sure your stock and canned tomatoes are onion and garlic free!
- Low Nickel: Avoid black beans, opt for dried and rehydratred lentils if tolerated, and be cautious with canned products — people with systemic nickel allergy often react to canned goods.
- Top 8 Allergen-Free: This recipe contains no dairy, eggs, wheat/gluten (if you use gluten-free tortillas), soy, nuts, fish, or shellfish. Check your stock and canned ingredients for hidden allergens.
- Vegetarian/Vegan: Substitute the meat with lentils, crumbled tofu, or a mix of mushrooms and walnuts (if tolerated), and use vegetable stock.

Frequently Asked Questions (FAQs)
Can I make this ahead and store it in the fridge instead of freezing?
Yes! Store in an airtight container in the fridge for up to 4 days. Reheat portions as needed in the microwave or on the stovetop.
Is this recipe spicy?
I don’t find it spicy, but if you’re very sensitive you might notice a mild heat from the chili powder – feel free to leave it out or add more to taste. If you want extra spice try top with jalapeños or your favorite hot sauce!
Can you recommend any Low FODMAP hot sauces to go with this?
Yes! Some of my favourite low FODMAP hot sauces are Tobasco and Cholula original! I’ve heard that FODY Foods hot sauce is also good!
Can I use something other than white rice?
Absolutely. Quinoa works well and adds extra protein – just par-cook it separately before adding to the filling. Brown rice and wild rice are also great low FODMAP alternatives that work directly in the recipe.
What vegetables can I add?
Zucchini, grated carrot, or baby spinach are great additions for extra veggies. Just stir them in during the last few minutes of cooking.
Is this good for meal prep lunches?
Yes! It reheats beautifully and pairs well with fresh toppings. Add to lunchboxes with rice and a side salad or tortillas.
