This tuna butter spread is rich, flavorful, and ready in about five minutes—a truly satisfying breakfast that will keep you full until lunchtime.

Premium tuna is paired with ripe avocado, crisp cucumber, fresh herbs, and a hint of lemon. It's rich but not heavy and goes well with toast, sandwiches, or straight from a cracker jar.

If you're looking for a tuna sandwich that isn't drowned in mayo, this is it. And if you love the melt-in-your-mouth tuna spread, this similar method works just as well, only adding cheese and pan-frying.

This technique borrows a bit from the guacamole method with mashed avocado; it's just creamy enough but leaves a little bulk for texture. That's why it feels firm rather than like a dough.

Ingredients:

1 avocado
1/2 lime juice
5oz/1 can can of yellow tuna
2 eggs
1/3 cup chopped cucumber
1/4 cup diced red onion
Cilantro
1 teaspoon Dijon mustard
1/2 teaspoon garlic flakes
1/4 teaspoon red chili flakes
Salt
1 tablespoon butter mayo
2 sourdough breads
Cheddar cheese

This is a truly high-protein instant breakfast and one of my go-to quick instant breakfast options for busy mornings. If you're collecting avocado sandwich recipes or looking for more avocado breakfast recipes and avocado recipes in general, this one is in the swing of things.

It also pairs great with poached eggs if you're eating healthy meals with eggs or healthy egg recipes for weight loss; that combination is hard to beat.

Whether you're looking for healthy and delicious breakfast recipes, tasty and healthy breakfast ideas, healthy meals with avocado, fresh and delicious breakfast recipes for the morning, or just more solid healthy breakfast ideas, this spread has something for you.
