Ingredients

  

• 1 –2 cans sardines in olive oil drained, reserve a little oil
• 1 large ripe tomato finely diced
• ½ small red onion finely diced (soaked if you want milder flavor)
• ½ cup fresh cilantro chopped

3. Squeeze in fresh lime juice, season with salt and pepper, and toss gently.
4. Let sit for 5–10 minutes so the flavors blend.

6. Drizzle with reserved oil, garnish, and serve immediately.

Notes

Why This Works for Blood Sugar

This recipe supports steady blood sugar because it combines:

• Healthy fats (sardines + avocado) → slow digestion
• Fiber from vegetables → helps reduce spikes
• Lower total carbs → better glycemic control

It’s a simple way to build a balanced plate without overthinking it.

Tips for Best Flavor

• Use fresh lime juice—this is the main flavor
• Keep the jalapeño minimal for balance, not overpowering heat
• Add avocado last so it stays creamy
• Taste and adjust—this should be citrus-forward and fresh

Variations (Keep It Low-Carb)

• Add chopped shrimp for extra protein
• Swap jalapeño for a pinch of chili flakes for milder heat
• Add diced bell peppers for crunch without extra carbs
• Serve over lettuce instead of chips

How to Serve

• Eat it straight from the bowl
• Spoon into lettuce wraps
• Serve with cucumber slices or low-carb crackers
• Add to a protein bowl for a fuller meal
