Ingredients

- Green pepper: Adds crisp green flavor and a boost of vitamin C choose one that feels heavy and glossy
- Red pepper: Brings sweetness and even more color to each bite
- Red onion: Gives sharp spicy flavor slice thin with a sharp knife or mandoline to avoid harshness
- English cucumber: Crunchy and nearly seedless plus the skin is tender so no peeling required
- Grape tomatoes: Sweet and juicy halve for even distribution and best texture
- Sliced olives: Savory brininess that wakes up all the other flavors choose a can with firm unbroken slices
- Cheddar cheese: Cubes give creamy pockets through the salad I love using extra sharp

I always look forward to the cubes of sharp cheddar in this They remind me of my grandmother who swore extra cheese was her secret to winning over picky cousins at reunions
